Infant Baptism & Jewish Proselyte Baptism

A significant parallel exists between Jewish proselyte baptism (when pagans were converted to Judaism) and early Christian baptism. The contacts between early Christian baptism and proselyte baptism, with the similarities in terminology, interpretation, symbolism, and the rite itself, are especially notable. What is of greatest interest, however, is that the baptism of the early Church followed that of proselyte baptism, in which children and infants were baptized with the convert’s family. This is especially significant when one realizes that the very early Church was made up primarily of converted Jews.
