This led to infant baptism. At first the infants were immersed, for until this time immersion was the only method of baptism known. By the 4th century, Constantine had formed the Roman Catholic Church, and in 416 A.D., infant baptism was established by law. The Protestants who teach baptismal regeneration, infant baptism, and sprinkling, are merely following the example of the roman Catholic Church. The three doctrinal errors listed above, violate the first three requirements for scriptural baptism.
Scriptural baptism requires the saved to be baptized.
Infant baptism requires little infants who are unable to bear and believer to be baptized, but scriptural baptism requires that believers only be baptized. Since Protestant denominations came out of the Roman Catholic church, it is not surprising that all of them contend for one or more of the above doctrinal errors. The Lutherans, Episcopalians, Presbyterians and Methodists all sprinkle infants, and all believe in some form of baptismal regeneration. Baptists are not Protestants, but have existed in every century since the 1st century. Baptists cannot accept the baptism of churches that are wrong on the matter of salvation.
