Judaizers is predominantly a Christian term, derived from the Greek verb ioudaïzō (ἰουδαΐζω "live according to Jewish customs", see ioudaioi). This term is most widely known from the single use in the Greek New Testament (Galatians 2:14) where Paul publicly challenges Peter for compelling Gentile believers to "judaize", also known as the Incident at Antioch.
According to the Concise Oxford Dictionary of World Religions (1977) this term includes groups such as Jewish Christians, Quartodecimans, Ethiopian Christians, descendants of English Puritanism such as the Seventh-day Adventist Church and others, who claim the necessity of obedience to the Mosaic Laws which are found in the first five books of the Christian Old Testament, though this is something likely disputed by members belonging to these groups, notably the Seventh-day Adventist Church, as the term Judaizers is typically used as a pejorative.
The issue of the Old Covenant in Christianity is complex and controversial, however, most traditional Christians believe much of it has been superseded while some modern Protestants believe it has been completely abrogated and replaced with the Law of Christ. Thus, "one who has Judaized", refers to a Christian who has accepted the necessity of adhering to the Mosaic Laws or to specific laws that are believed to be superseded, such as circumcision, Sabbath observance, or observation of the Passover. The ongoing Christian debate over "Judaizing in Christianity" began in the lifetime of the apostles, notably at the Council of Jerusalem and Incident at Antioch, and parallels the ongoing debate about Paul of Tarsus and Judaism, Protestant views of the Ten Commandments, and Christian ethics.
There is also a parallel to the debate within 1st and 2nd century Judaism as to the place of Gentiles with regard to the Torah. The outcome of that debate was that Rabbinic Judaism determined that gentiles need only follow a small subset of the Torah, called the Seven Laws of Noah, to be assured of a place in the world to come.
Distinct uses of the term "Judaizers" 
- Adherence by Gentile Christians to the Torah Laws originally given to the Israelites (i.e. the 613 Laws given to Israel at Sinai). That Gentile Christians should convert to Judaism and obey the Laws of Moses was the assumption of some in the Early Church, represented by Pharisees who had become believers in Acts 15 (Acts 15:5). This was the Jewish Christian version of the opinion within Judaism that Gentiles should convert to Judaism in order to be right with God (see convert to Judaism). This opinion is traced by some scholars to a faction within early Christianity after the crucifixion of Jesus led by Jesus' brother James the Just (though compare Acts 15:24). Saint Paul opposed this position, with a Jewish Christian version of the opposite opinion in Judaism that Gentiles did not need to convert and obey the entire Law of Moses. See also Hellenistic Judaism. This conflict between Saint Paul and his opponents was the reason for the Council of Jerusalem (see Acts 15:1–35). Here James, Paul, and the other leaders of the early Christian movement agreed that Gentile converts needed only to follow the "three exceptions" (Acts 15:20,29; counted by some as four), laws that roughly coincide with Judaism's Seven Laws of Noah said to be established by God for all humankind (see also Genesis 9:1–17). This Apostolic Decree, still observed by the Orthodox Church, is similar to that adopted by Rabbinic Judaism, which teaches that Gentiles need only follow the Noachide Laws to be assured of a place in the World to Come. See also Dual-covenant theology.
- Adherence by Gentile Christians to Torah Laws intended for Gentiles. The "three exceptions" resolved by the Council of Acts 15 indicate that the apostles accepted that those portions of the Law of Moses (the Torah) intended for Gentiles (later known as the Laws of Noah) would apply to Gentile Christians. Extra-Biblical evidence shows that, at least in some areas (especially in the East), this included observances beyond the three exceptions, such as a Christianized form of Passover, Day of Atonement, and Sabbath. But other Gentile Christian communities (especially in the West), evolved in an increasingly anti-Jewish direction that interpreted Paul's teaching to mean that all Torah Laws are redundant "now that Salvation by Faith is available through Jesus' atoning death". From this latter point of view, any practice associated with Judaism came to be seen as a rejection of God's salvific gift, even the prohibition of blood which is listed among the "three exceptions" in Acts 15 (though the prohibition of blood was only rejected in the Western Church and not until the Middle Ages). While Acts 15 gives an example of what new Believers were subject to when entering the house of God, verse 21 states that the Gentiles would learn the ways of Moses the way it's been done. The prohibitions against fornication and idolatry are still observed by most Christian denominations even though they originated as Jewish law. See also Antinomianism and Marcionism and The Law of Christ.
- Continuance of observance of Torah by Jews who have (willingly or forcibly) converted to Gentile Christianity. This behavior was particularly persecuted between 1300 and 1800 under the Spanish and Portuguese Inquisitions, using as a basis the many references in the Pauline epistles regarding the "Law as a curse" and the futility of relying on the Law for attaining salvation, known as legalism. Thus, in spite of Paul's agreement at the Council of Jerusalem, Gentile Christianity came to understand that any Torah Laws (with the exception of the Ten Commandments and Natural Law) were anathema, not only to Gentile Christians but even to Christians of Jewish extraction. Under the Inquisition, the penalty to a converted Jew for "Judaizing" was usually death by burning.
References over time 
The Latin verb iudaizare is used once in the Vulgate where the Greek verb ioudaizein occurs at Galatians 2:14, and this was used by Augustine in his Commentary on Galatians, describing Paul's opposition in Galatia as those qui gentes cogebant iudaizare - "who though to make the Gentiles live in accordance with Jewish customs."
The Spanish verbal participle Judaizante was applied both to Jewish conversos to Catholicism who practiced Judaism secretly and sometimes to Jews who had not converted, in Spain and the New World at the time of the Spanish Inquisition.
In current day, the term can be used also to describe a subset of Messianic Jews who believe that Gentiles and Jews must follow the entire Sinai Law in addition to accepting Jesus as messiah. This approach is reminiscent of the original position of James, recorded in Acts (although James subsequently rectified this approach, per his decision of Acts 15:1–35). There are two possible rationales for this approach: (a) either it is understood that Gentiles and Jews are commanded by the Torah and New Testament to follow the entire Sinai Law, or (b) it is understood that in coming to Jesus all Gentiles become part of Israel and therefore must follow the entire Sinai Law.[original research?]
Origin of the word 
But when I saw that they are not walking uprightly to the truth of the good news, I said to Peter before all, `If thou, being a Jew, in the manner of the nations dost live, and not in the manner of the Jews, how the nations dost thou compel to Judaize?
The meaning of the verb Judaize, from which the noun Judaizer is derived, can only be derived from its various historical uses. Its Biblical meaning must also be inferred and is not clearly defined beyond its obvious relationship to the word "Jew." The Anchor Bible Dictionary, for example, says: “The clear implication is that gentiles are being compelled to live according to Jewish customs."
But when I saw that they were not acting consistently with the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?" (NRSV)
Besides other taxes, that on the Jews [A tax of two drachmas a head, imposed by Titus in return for free permission to practice their religion; see Josephus, Bell. Jud. 7.6.6] was levied with the utmost rigor, and those were prosecuted who, without publicly acknowledging that faith, yet lived as Jews, as well as those who concealed their origin and did not pay the tribute levied upon their people [These may have been Christians, whom the Romans commonly assumed were Jews]. I recall being present in my youth when the person of a man ninety years old was examined before the procurator and a very crowded court, to see whether he was circumcised. (Suetonius on Domitian 12.2, Rolfe Translation).
It occurs once in the Apostolic Fathers collection, in Ignatius's letter to the Magnesians 10:3 written around the year 100:
There are several direct interpolations by a later forger regarding anti-Judaizing in Ignatius's epistles that are considered authentic, it can be assumed the redactor was either trying to build upon Ignatius' positions or responsible for what is perceived as Ignatius' anti-Judaizing altogether.
It occurs once in the Acts of Pilate, chapter 2, roughly dated from 150 to 400:
And Pilate, summoning the Jews, says to them: You know that my wife is a worshipper of God, and prefers to adhere to the Jewish religion along with you... Annas and Caiaphas say to Pilate: All the multitude of us cry out that he [Jesus] was born of fornication, and are not believed; these [who disagree] are proselytes, and his disciples. And Pilate, calling Annas and Caiaphas, says to them: What are proselytes? They say to him: They are by birth children of the Greeks, and have now become Jews. (Roberts-Donaldson Translation).

It is widely held that Paul accused Judaizers of teaching that observance of the Abrahamic ritual was necessary to be justified and hence saved, i.e. Legalism, (see also Circumcision controversy in early Christianity and for a counterview, see New Perspective on Paul). The relationship of Paul of Tarsus and Judaism is still disputed today. These groups taught that Gentile followers of Jesus needed to become Jewish proselytes and by so doing also observe the various requirements of the written Torah.
According to Eusebius' History of the Church 4.5.3-4: the first 15 Bishops of Jerusalem were "of the circumcision", although this in all likelihood is simply stating that they were Jewish Christians (as opposed to Gentile Christians), and that they observed Biblical circumcision and thus likely the rest of Torah as well.
The issue was an early source of controversy in the church of and came to a head during the Council of Jerusalem. According to the account given in Acts 15, it was determined that Gentile converts to Christianity did not have to go through the proselyte ritual (circumcision) to secure a place in the World to Come; but in addressing the second question as to whether or not they should obey the Torah they encouraged the Gentiles to "abstain from things sacrificed to idols, and from blood, and from things strangled, and from fornication,"
Paul also addressed this question in his Epistle to Galatians in which he condemned those who insisted that the proselyte ritual had to be followed for justification as "false believers" (Galatians 2:4):
But even Titus, who was with me, was not compelled to be circumcised, though he was a Greek. But because of false believers secretly brought in, who slipped in to spy on the freedom we have in Christ Jesus, so that they might enslave us – we did not submit to them even for a moment, so that the truth of the gospel might always remain with you. And from those who were supposed to be acknowledged leaders (what they actually were makes no difference to me; God shows no partiality) – those leaders contributed nothing to me. On the contrary, when they saw that I had been entrusted with the gospel for the uncircumcised, just as Peter had been entrusted with the gospel for the circumcised (for he who worked through Peter making him an apostle to the circumcised also worked through me in sending me to the Gentiles), and when James and Cephas and John, who were acknowledged pillars, recognized the grace that had been given to me, they gave to Barnabas and me the right hand of fellowship, agreeing that we should go to the Gentiles and they to the circumcised. They asked only one thing, that we remember the poor, which was actually what I was eager to do. . . . We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is justified not by the works of the law but through faith in Jesus Christ. And we have come to believe in Christ Jesus, so that we might be justified by faith in Christ, and not by doing the works of the law, because no one will be justified by the works of the law. (Galatians 2:3–10, 15-16 NRSV)
Also Paul warned the early Galatian church that Gentile Christians who submit to circumcision will be alienated from Christ: "2 Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing. 3 And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law. 4 You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace." (Galatians 5:2–4). The Epistle to Titus 1:11, often attributed to Paul, is, according to some Biblical scholars, also a condemnation of these practices. Paul is against only the practice of circumcising oneself, and this is not actually a Law in the Torah, as the Law is to circumcise one's son, hence is why he brings up the issue of Abraham. It is commonly mistaken that Paul is grouping all of Jewish Law with the unrequired self-circumcision that the "Circumcision Faction" was attempting to press on fresh converts. But Paul clearly says that the Law is to be upheld. (Romans 2:13, 3:31, Galatians 3:12).
The influence of the Judaizers in the church diminished significantly after the destruction of Jerusalem, when the Jewish-Christian community at Jerusalem was dispersed by the Romans during the Great Jewish Revolt. The Romans also dispersed the Jewish leadership in Jerusalem in 135 during the Bar Kokhba Revolt. Traditionally it is believed the Jerusalem Christians waited out the Jewish–Roman wars in Pella in the Decapolis. These setbacks however didn't necessarily mean an end to Jewish Christianity, any more than Valerian's Massacre of 258, (when he killed all Christian bishops, presbyters, and deacons, including Pope Sixtus II and Antipope Novatian and Cyprian of Carthage), meant an end to Roman Christianity.
Christian groups following Jewish practices never completely vanish, although they had been designated as heretical by the 5th century. Old Testament practices are still practiced among Gentiles to this day, including circumcision (see also Biblical law in Christianity). The Coptic churches continue to practice circumcision, but critics charge this may reflect ancient Egyptian influence or be a response to the culture of the Islamic majority (see also Abrahamic religions and Circumcision controversy in early Christianity). In Torah-submissive Christian groups which include the Ethiopian Orthodox church, dietary laws and Saturday Sabbath are observed as well.
Jewish Encyclopedia: Gentiles: Gentiles May Not Be Taught the Torah makes the following observation:
R. Emden (), in a remarkable apology for Christianity contained in his appendix to "Seder 'Olam" (pp. 32b-34b, Hamburg, 1752), gives it as his opinion that the original intention of Jesus, and especially of Paul, was to convert only the Gentiles to the seven moral laws of Noah and to let the Jews follow the Mosaic law— which explains the apparent contradictions in the New Testament regarding the laws of Moses and the Sabbath.
In the 2nd century, Marcion opposed all Judaizers. According to the 1911 Encyclopædia Britannica article on Marcion: "It was no mere school for the learned, disclosed no mysteries for the privileged, but sought to lay the foundation of the Christian community on the pure gospel, the authentic institutes of Christ. The pure gospel, however, Marcion found to be everywhere more or less corrupted and mutilated in the Christian circles of his time. His undertaking thus resolved itself into a reformation of Christendom. This reformation was to deliver Christendom from false Jewish doctrines by restoring the Pauline conception of the gospel, Paul being, according to Marcion, the only apostle who had rightly understood the new message of salvation as delivered by Christ. In Marcion's own view, therefore, the founding of his church—to which he was first driven by opposition—amounts to a reformation of Christendom through a return to the gospel of Christ and to Paul; nothing was to be accepted beyond that. This of itself shows that it is a mistake to reckon Marcion among the Gnostics. A dualist he certainly was, but he was not a Gnostic." But like the Gnostics, Marcion believed that the Jewish God Yahweh had created the world, was lesser in status to the unreachable higher God, and was evil, see also Dualism. Against this view, Irenaeus of Lyons's Against Heresies 3.12 section 12 ridiculed those who think they are wiser than the Apostles because they were still under Jewish influence.
Judaizing teachers 
The Judaizing teachers were a group of Jewish Christians who taught that converts to Christianity must first be circumcised (i.e. become Jewish through the ritual of a proselyte) in order to observe the Law of Moses (as well as the oral traditions of the authorities making the proselyte ritual mandatory for Gentiles to secure a place in the World to Come) in order to be justified. This group was very active in the church of the 1st century AD prior to the destruction of the Temple of Jerusalem in the Great Jewish Revolt. Although such requirements may have made Christianity a much less appealing religious choice for some Gentiles, the evidence afforded in Paul's letter to the Galatians exhibits that a significant number of the Galactic Gentile converts appear readily disposed to adopt these nomistic requirements; indeed, Paul strenuously labors throughout the letter (cf. Gal 5:4; 4:21; 5:2,3)to dissuade them from doing so.
Paul saw these teachers as being both dangerous to the spread of Christianity and propagators of grievous doctrinal error. Many of his letters included in the New Testament (the Pauline epistles) contain considerable material disputing the view of this group and condemning its practitioners. In 2 Corinthians 11:5 and 12:11 he called his opponents super-apostles. Also, in 2 Corinthians 11:13 -15 Paul refers the Judaizers as False Apostles. Paul publicly condemned Peter for his seemingly ambivalent reaction to the Judaizers, embracing them publicly in places where their concepts were popular while holding the private opinion that the teachings were erroneous, for example 1 Cor 9:20–23.
The Catholic Encyclopedia: Judaizers notes: "Paul, on the other hand, not only did not object to the observance of the Mosaic Law, as long as it did not interfere with the liberty of the Gentiles, but he conformed to its prescriptions when occasion required (1 Corinthians 9:20). Thus he shortly after circumcised Timothy (Acts 16:1–3), and he was in the very act of observing the Mosaic ritual when he was arrested at Jerusalem (21:26 sqq.)."
Judaizing teachers are even more strongly condemned in the Epistle of Barnabas. (Although it did not become part of the Christian Biblical canon, it was widely circulated among Christians in the first two centuries and is part of the Apostolic Fathers.) Whereas Paul acknowledged that the Law of Moses and its observance were good when used correctly ("the law is good, if one uses it lawfully", 1 Tim 1:8), the Epistle of Barnabas condemns most Jewish practices, claiming that Jews had grossly misunderstood and misapplied the Law of Moses.
Later effects of Judaizer controversy 
At various times since the second half of the 15th-century, the Russian Orthodox Church has described several related heretical groups as having a Judaizing character; the accuracy of this label – which was influenced by the early Christian polemics against Judaizers – has been disputed. (See Sect of Skhariya the Jew.)
