Many mainstream Protestant churches changed their official stance on issues such as abortion and contraception in the 1970’s shortly after Roe v Wade. There was EXTREME pressure on the Church to change her position on contraception at this time as well. The pill was well on its way to being common place and there was an unprecedented amount of pressure on the Church to say Catholics could use it. A multi-disciplinary commission that had been setup by the Pope to review this issue came to him with an overwhelming majority saying that contraception was morally acceptable. They did not know at this time that the pill had abortive capabilities that would have completely undermined the Church’s teaching that life begins at conception. If the Pope had followed the advice of the commission the Church would have later been found to have given its support to something that so blatantly went against her teachings that life begins at conception. The Church could have said it was misled by scientific evidence, be we all know how much this would have hurt the Church’s credibility and infallibility teaching.
So my point is this: divine protection or blind luck?
