But to claim there is no scriptural basis for teaching that birth control is immoral is simply beyond credulity.
Christianity has always, unanimously declared that contraception is inherently wrong, based on the Onan incident and Natural Law.
Its only within the last 80 years, but primarily since 1960, that Protestantism has reinterpreted these issues to say that contraception is morally licit.
When Christian moral theology unanimously teaches that something is inherently evil, then certain subsets of Christianity only in the last several generations claim otherwise, that is by definition proof of apostasy in moral theology, one's personal interpretation of scripture notwithstanding.
If we disagree with the entire patrimony of Christianity on this issue, we cannot possibly be correct, and we must examine ourselves to find our error.
I am reading Father Thomas Euteneuers book Demonic Abortion. In it he writes that the culture of deaths unholy trinity is abortion, contraception and comprehensive sex education.
