What the Church cannot change

The Church has no authority whatsoever to overturn the teaching on abortion, contraception, the male-only priesthood, or divorce and “remarriage.”  We have no authority to overthrow biblical doctrines, Sacred Tradition, or any of our defined dogmas and doctrines. Something cannot be morally or doctrinally true one day and untrue the next. Some still insist that the Church should read the surveys and change her teachings.
