NFP
is birth control. It regulates birth by monitoring the natural periods of fertility and infertility that God designed into women. The Church officially teaches that couples should have (depending upon the Latin translation) “just” “grave” or “serious” reasons if they try to avoid pregnancy. If such reasons exist, the couple may use NFP licitly and avoid relations during the woman’s fertile times.
On the other hand,
artificial birth control (aka contraception or ABC) for the purpose of avoiding pregnancy on the other hand is objectively a mortal sin; ABC is
always illicit. Persons in mortal sin should not recieve Holy Communion until they have repented and gone to confession.
