The name Anabaptism derives from Greek terms for re-baptism (Greekανα (again, twice) +βαπτιζω (baptize), thus "re-baptizers") and was originally used as a pejorative term. Anabaptists require that candidates be able to make their own confessions of faith and so refuse baptism to infants. As a result, they were heavily persecuted during the 16th century and into the 17th by both other Protestants and Roman Catholics.
Believer's baptism (occasionally called credobaptism, from the Latin word credo) is the Christian practice of baptism as this is understood by many Protestant churches, particularly those that descend from the Anabaptist tradition. According to their understanding, a person is baptized on the basis of his or her profession of faith in Jesus Christ and as admission into a local community of faith.
The contrasting belief, held in other Christian churches, is infant baptism (pedobaptism or paedobaptism, from the Greek paido meaning “child”), in which infants or young children may be baptized upon the request of a parent who professes faith.
Baptisms are performed in various ways: believer's baptism by immersion and infant baptism by affusion or aspersion or immersion. Believer's baptism is often erroneously referred to as adult baptism, even though children may be baptized so long as they are old enough to earnestly profess their faith. (More...)
Born in approximately 1490 in Staufen, Germany. Sattler became a Benedictine monk in the cloister of St. Peter and most likely became prior. He left St. Peter's probably in May 1525 when the monastery had been overcome by the troops from the Black Forest fighting in the peasant's war. He later married a former Beguine named Margaretha. When Sattler arrived in Zurich is not known except that he was in town before being expelled from the city November 18, 1525 in a wave of expulsions of foreigners resulting from the November 6-8 disputation on baptism. Some believe that Sattler is to be identified as the "Brother Michael in the white coat," mentioned in a document dated March 25 of that year, thus placing Sattler in Zurich before Snyder's estimation of when he left St. Peter's. Snyder believed that Sattler possibly arrived in Zurich to attend that disputation.
