The Catholic objection to birth control is that it is wrong to artificially deprive sexual intercourse of its most important natural function, which is reproduction. The way they see it, when you use a condom, you are having an intimate encounter with a piece of plastic, not a human being. Abortion is completely different since it destroys an embryo or fetus that already exists, rather than preventing the formation of one. Most Christians hold that a fetus is either a human being, or something so close to a human being that it has nearly the same rights. If you believe that a premature baby is a person, then you must believe that a fetus is also a person, because they are the same thing.
Christians provide various kinds of practical assistance to women faced with unexpected pregnancies.
Christians do not believe that a woman's body is her own. Our bodies belong to God, not ourselves. Christians believe that men as well as women must take responsibility for the effects of their sexual activities. The controversies that exist outside the Christian community also exist within it. Naturally, Christian morality sets some limits, but it does not prescribe a specific form of government or specific government policies.
