Looks like the thread was deleted. I guess they can handle only so many truth bombs and handle so much logic before they just wished it all went away.
Personally, I really took issue with several of them calling all "Protestants" essentially heretics whose beliefs are innovations and are cherry picked, but when it could be shown from their own venerated Church Fathers that their beliefs are inconsistent with ancient practice their heads exploded.
The point I wanted to make clear to them that if God's standards are perfection, (their talk of "getting closer to God" or becoming God/theosis), that no amount of sacraments gets them any closer or better with God. It is a rather simple notion really.
What makes us better with God? Only one thing can, and it is equally available to all: faith in Christ. Satan will devise systems to distract us from Christ's finished work on the cross, but what Jesus did for us leaves us know doubt. He has paid our full penalty. There is no increasing righteousness in the eyes of God that we get from obedience, for in God's judgement we are completely righteous when we are found hidden with Christ in God.
Sacraments cannot save and do not save. If you trust in the sacraments that cannot save, you will find that the One who can save will not know you when its too late.
