Retroactively. Or at least that's how some might characterize it.
Mike Aquilina is posting about a feature story in a Greek newspaper concerning the use of contraceptives and abortifacients in antiquity. He points out the Fathers' consistent condemnation of both and notes that Christian condemnation of these evils only came about in the 20th century. My knowledge of the writings of the early Church fathers isn't anywhere close to the depth of Mike's, but a quick look at the first century Didache is enough to put the lie to claims by dissenters that the Church never taught on such matter until as recently as the 1960s.
You (all six or seven of you) might recall that I posted on the topic of contraception a few months back. Pope Paul VI wrote prophetically in Humanae Vitae about the secondary effects of contraception. I think history already bears out the wisdom of his words; science, to a smaller degree, appears to be following.
