 Official Roman Catholic doctrine opposes all non-natural birth control, birth control devices and all intentional abortions (Pope Paul VI, 1968, Humanae Vitae). Some regard human sexuality as having an essentially reproductive purpose and artificial birth control as unethically unnatural. Like Roman Catholics, other religious faith communities subscribe to a belief that human life begins “at the moment of conception” when a sperm fertilizes an egg, and that forms of birth control that may prevent the development of a fertilized egg to grow into a baby are the moral equivalents of intentional “abortion”. Those who oppose contraception on personal moral or religious grounds, sometimes but not always, support a legal “right to privacy” ; protecting access to medically safe birth control and/or abortion.
