Assurance is a Protestant Christian doctrine that states that the inner witness of the Holy Spirit allows the justified disciple to know that he or she is saved. Based on the writings of St. Augustine of Hippo, assurance was historically a very important doctrine in Methodism, Lutheranism, and Calvinism, and remains so among some members of these groups today.
John Wesley and Methodism
John Wesley believed that all Christians have a faith which implies an assurance of God's forgiving love, and that one would feel that assurance, or the "witness of the Spirit". This understanding is grounded in Paul's affirmation, "...ye have received the Spirit of adoption, whereby we cry Abba, Father. The same Spirit beareth witness with our spirits, that we are the children of God..." (Romans 8:15-16, Wesley's translation). This experience was mirrored for Wesley in his Aldersgate experience wherein he "knew" he was loved by God and that his sins were forgiven.
- "I felt my heart strangely warmed. I felt I did trust in Christ, Christ alone for salvation, and an assurance was given me that He had taken my sin, even mine." - from Wesley's Journal
Early in his ministry Wesley had to defend his understanding of assurance. In 1738 Rev. Arthur Bedford had published a sermon in which he misquoted Wesley's teachings. Bedford had understood Wesley as saying that a Christian could be assured of persevering in a state of salvation, the Calvinist view.
In a letter dated September 28, 1738 Wesley wrote, "The assurance of which I alone speak I should not choose to call an assurance of salvation, but rather (with the Scriptures), the assurance of faith. . . . [This] is not the essence of faith, but a distinct gift of the Holy Ghost, whereby God shines upon his own work, and shows us that we are justified through faith in Christ...The 'full assurance of faith' (Hebrews 10.22) is 'neither more nor less than hope; or a conviction, wrought in us by the Holy Ghost, that we have a measure of the true faith in Christ..'"
Lutheranism accepts monergism, which states that salvation is by God's act alone, and rejects the teaching that humans in their fallen state have a free will concerning spiritual matters. Lutherans believe that although humans have free will concerning civil righteousness, they cannot work spiritual righteousness without the Holy Spirit, since righteousness in the heart cannot be wrought in the absence of the Holy Spirit. Lutherans believe that the elect are predestined to salvation. According to Lutheranism, Christians should be assured that they are among the predestined. Lutherans believe that all who trust in Jesus alone can be certain of their salvation, for it is in Christ's work and his promises in which their certainty lies. However, they disagree with those that make predestination the source of salvation rather than Christ's suffering, death, and resurrection. Unlike Calvinists, Lutherans do not believe in a predestination to damnation. Instead, Lutherans teach eternal damnation is a result of the unbeliever's sins, rejection of the forgiveness of sins, and unbelief. The central final hope of the Christian is "the resurrection of the body and the life everlasting" as confessed in the Apostles' Creed, but Lutherans also teach that, at death, Christian souls are immediately taken into the presence of Jesus in heaven, where they await this bodily resurrection and the second coming of Jesus on the Last Day.
Calvinism and Reformed theology
Calvinism teaches that believers may have assurance of their salvation especially through the work of the Holy Spirit and also by looking at the character of their lives. The idea that because good works necessarily result from true faith one can gain assurance by observing evidences of faith in their life is called the practical syllogism. If they believe God's promises and seek to live in accord with God's commands, then their good deeds done in response with a cheerful heart provide proof that can strengthen their assurance of salvation against doubts. This assurance is not, however, a necessary consequence of salvation, and such assurance may be shaken as well as strengthened.
...infallible assurance doth not so belong to the essence of faith but that a true believer may wait long and conflict with many difficulties before he be partaker of it: yet, being enabled by the Spirit to know the things which are freely given him of God, he may, without extraordinary revelation, in the right use of ordinary means, attain thereunto. And therefore it is the duty of everyone to give all diligence to make his calling and election sure; that thereby his heart may be enlarged in peace and joy in the Holy Ghost, in love and thankfulness to God, and in strength and cheerfulness in the duties of obedience, the proper fruits of this assurance...
Additionally, the Augustinian doctrines of grace regarding predestination are taught in the Reformed churches primarily to assure believers of their salvation since the Calvinist doctrines emphasize that salvation is entirely a sovereign gift of God apart from the recipient's choice, deeds, or feelings (compare perseverance of the saints).
The Catholic Church teaches that an infallible certitude of final salvation, as supposed in Calvinism, is not a usual experience, as seen in the sixteenth canon of the sixth session of the Council of Trent:
"If any one saith, that he will for certain, of an absolute and infallible certainty, have that great gift of perseverance unto the end,-unless he have learned this by special revelation; let him be anathema."
In critiquing the Reformed doctrine of the assurance of salvation, prominent Catholic apologist Robert Sungenis notes a problematic complication of the doctrine as it relates to the historic Protestant doctrine of Sola fide:
"The burden is on the Reformed position because it says that a person can live his whole life thinking that he is justified by faith alone and yet come to the point in time where he stands at the judgment seat of God and finds out that he or she did not have the works that qualified the faith to be justifying faith and therefore God would say, 'I’m sorry, you were never justified in the first place.' So, if there’s anyone who lives under a cloud of terror, it’s the Reformed Protestant because he or she never knows if he or she (or God) did the proper works in order to qualify the faith that he or she needs for justification. And this is especially important because the Reformed position says that works can never enter into the faith that procures the justification because works are all in sanctification. So, if works can never enter into the faith that one needs for justification how can they ever qualify the faith that one needs for justification? So, now there is a double-dilemma."
Catholics recognize that a certainty of faith is ascribed to St. Paul (2 Cor 12,9) and speculate that the Virgin Mary also probably possessed it. Jesus Christ as man, however, did not need to believe since he knew it. Ludwig Ott argues that a high moral, human certainty of having sanctifying grace is possible, on the grounds that one is not conscious of an unforgiven grave sin, but by no means faith which is believing with divine certainty and that with some probability one can locate positive signs of predestination, which does not mean that their lack be a sign of reprobation: He lists persistent action of the virtues recommended in the Eight Beatitudes, frequent Communion, active charity, love for Christ and the Church and devotion to the Blessed Virgin. Moreover and especially, a Catholic can, and should, have certain hope for eternal salvation, which does not rest chiefly on a grace already received, but rather on prospective future forgiveness by God's omnipotence and mercy. The point in question is that however certain, the hope must retain its proper name and not be confused with faith. If together with a determination for sin, this hope is in danger of giving way to presumption.
In the Catholic tradition, a close equivalent to a doctrine of assurance has been a doctrine of final perseverance. Compliance with First Friday Devotions has sometimes been taught as a means to final perseverance.
