The Human Sacrifice. This is the Unveiling of Roman Catholicism, part 5 of 7. The official Roman Catholic doctrine of salvation is that the grace of God is infused into a baby at baptism -- making him/her justified before God. This justification can be lost through sin and must be regained by repeated participation in the many sacraments found in the Roman Catholic Church. As long as the Roman Catholic Church continues to assert its own authority and bind its people to “another gospel,” it is the spiritual duty of all true Christians to oppose Roman Catholic doctrine with biblical truth and to call all Catholics to true salvation.
