All of us are saved being basically ignorant and loaded down with baggage from our old lives. If one is saved while drinking, smoking, et cetera (we could name any particular sin or sins from our old lives), that doesn't mean immediately have a right Theological view or a right world view. This is usually accomplished over time in the process of Progressive Sanctification.
I will say that in our current time Doctrine and Practice has become a secondary issue for many. Don't we all search out the church that agrees with us? lol
We can be saved and ignorant, but we are commanded to learn of God, and when we do one of the most basic understandings is that murder is wrong. So in my opinion those who claim to have been saved for any length of time, if they are still supporting a godless worldview, should examine themselves, to see if they be in the faith or not. I think the church (not The Church), Modern Christendom, has suffered from a majority of false professions and been invaded by those who are not Christian...but merely religious. This is in large part due to the poor quality of leadership which is nothing new. This was the state when Christ arrived the first time, and it is without question that this will be the state prior to the Tribulation and His Second Coming.
Yes, one can be saved and be pro-choice, but...I do not believe the Lord will allow them
to remain that way.God bless.
