I feel I must address this for anyone who reads this thread later....
quote from Northwestern
"Do you believe everything your priest tells you about science? If he really believes that ALL forms of the pill are a form of a abortion, then he needs to do some serious and extensive reading on the matter BEFORE giving out advice to any more people. "Some" forms of the pill are a form of abortion, but not all. The classical form of the the contraceptive agent commonly known as "the pill" is well, a contraceptive. The "morning after pill" is of course as your priest described and believes, but certainly not all forms of the pill are. "
All chemical or hormonal methods of birth control act in several ways. The main way is by preventing ovulation. However, the secondary way they work is to make the lining of the uterus so thin that a developing embryo would not be able to implant and would be ejected from the body. The people who write about "the pill" are technically correct in saying that it non abortive, because in scientific definition, an embryo has to embed in order for it to be aborted from the body. However, if you believe life begins at conception, as is the Orthodox belief, then purposefully causing the embryo to die through lack of nourishment is abortive in the life-ending sense. The Pill is abortive, as are the various IUDs and anything but barrier methods.
