In other words, you can’t make an argument. Yeah, we already knew that.
What’s to argue? You want to go beyond that which ecumenical church (the church of the oikoumene) agreed before the eyes of the world to confess in the three ecumenical creeds. Further, you want to call into question the Christianity, the faith, of those unwilling to go beyond those universally accepted creeds. Further, you want to heap snark upon all such in the belief, apparently, that that will accomplish something God-pleasing (or self-pleasing, intellectual pride being what it is - there may not be a difference).
Well, Vladimir, I do not agree with you. Furthermore, I question what your goal really is. I will leave it at that since the rules of FR prohibit further speculation on my part ... and speculation is what it would be since only the Lord Himself knows the heart of each.
