"[T]here is a difference between birth control and contraception. "Birth control" can be applied to several different practices. It can indicate anything from the observance of continence, to conjugal acts during a woman's infertile period, to the use of contraceptive devices such as condoms or the pill. In certain circumstances the Church permits the regulation of births, yet in every circumstance the Church forbids contraception."
