I have asked for you to evaluate which Faith is more reasonable. The Bible does not explicitly reveal the Church’s acceptance of Baptism for infants, but it does implicitly reveal the Church’s acceptance of the practice, and the historical record reveals that the whole of Christianity accepted it as orthodox.
Within historical Christianity, as taught by Sacred Scripture and Sacred Tradition, and revealed by other historical documents, Baptism washes away an infant’s original sin, and it washes away both original sin and actual sin (volitional sin) for adults. The Protestant Church of Christ’s method washes away original sin even though the group does not realize it, and it also washes away the actual sin of its members who have attained the (biblically-absent, yet NI-forced) “age of accountability”.
The Catholic Church of Christ believes her infants share in the New Covenant, and, by the faith of our infants’ parents, we joyfully carry them to Jesus—even if such faith might only be the size of a mustard seed.
