Baptism, as taught by the Roman Catholic Church, is the Sacrament of spiritual rebirth by which one becomes 'born-again' and cleansed from all sins. This Roman Catholic teaching is in contradiction with the Roman Catholic Bible, which shows that Baptism was never administered to make a person a true believer, but was always something that was performed on those who were already born-again believers. The concept of baptismal regeneration, along with many other Roman Catholic teachings such as the Rosary and Purgatory, does not originate from within the Roman Catholic Church, but emanates from the bowels of Paganism.
