That line of reasoning was first used to embrace the use of artificial birth control.
Then it was used to embrace divorce and remarriage after divorce, first for the laity, then for the clergy.
Then and only then came the push for women’s ordination.
Good point, and one I had forgotten about (the birth control angle). Sadly, WELS is the only major synod I know of that actually takes a stand on the pill. Though I know a few LCMS pastors who are quietly questioning the synods view of birth control.
You are right. It does feed upon itself. The same methodology of what is called deconstructionism undermines not only the Scriptures but what Christians have believed, taught, and confessed for two thousand years. That is the problem with cultural relativism. Everything become relative including morals and commonsense.
Don’t forget abortion.
