"Christian ideas about contraception come from church teachings rather than scripture, as the Bible has little to say about the subject. As a result, their teachings on birth control are often based on different Christian interpretations of the meaning of marriage, sex and the family. Christian acceptance of contraception is relatively new; all churches disapproved of artificial contraception until the start of the 20th century. In modern times different Christian churches hold different views about the rightness and wrongness of using birth control."
