I have a had time imagining people who are not religious. The real difficulties with religion start when it gets organized. Then people decide that theirs is the best one, that their deities are the best ones, that their teachings are the best ones, etc. And, of course, those who don't buy into some organized religion must be pitied as hopelessly lost souls, and, if possible, have one forced on them. For their own good.
Even when there is only one set of teachings, groups will form according to who has the best interpretations, and of those sub-groups will form ... It is such interpretations that led to the "Christian church" to engage in a long history of crimes against humanity: "the Bible tells us that this is right and must be done" etc. And in individual life, even today, there are many who revel in their expert knowledge of teachings and focus on them to the point of forgetting that ultimately one of the key points is that it about humanity and relations between humans.
What's more, these interpretations, even the best and rightest and ***est change over time.
So in matters such as abortion, my view is that (beyond whatever law that is at hand) one's conscience should be as good a guide as "what the church" says. As far as Christianity goes, I will note that a key part in Christ's approach was a reaction against the likes of the Pharisees and their rigid and unhelpful interpretations of religious writings and teachings.
