Could you expand on that? I may be missing your point. Although I agree that there were many non-denominational quasi-Baptist churches (fundamentalist Bible-church types) that spotted the error right away. They just didn't get much press because they were single congregations. There were actually churches that were in favor of Roe (the idea, I guess, was fewer unwanted babies - but I cannot see it).
But on my original point. What Scriptural proof do we have that life begins at conception? My previous post was merely my opinion, I would love to see something definitive.
Why do ya need proof? If it does its a pretty serious matter if you're on the wrong side. If it doesn't, no harm no foul.
Many Protestant churches (mainline denominations) don't even officially believe God had much to do with the authoring of Scripture or if there is such an entity as God. There can be little surprise that they then declare such things as abortion to be "jim-dandy-fine" or homsexuality to be "normal." The real danger in Protestantism is not Sola Scriptura but the creeping liberalism of the Historical-Crits.
