I agree.
Even if Luther was right, how can he be justified condemning the very Church that passed on that faith to him to begin with?
Do we get our faith from our church or is it a gift from God?
The Church is the Body of Christ. I received that gift, faith, with no merit of my own, from Christ, acting through the Church, which is His Body. Although I am aware of defects in the human members of the Church, I see no advantage to condemning the Church; after that, there is anarchy.
