You are confusing infallible with impeccable. Peter had to be corrected by Paul. Should we therefore reject his epistles?
Why call me LORD, Lord if...
You are the ones who claim salvation by faith alone. I am glad to learn that you do not believe that anymore.
No, the Book Rome assembled so long ago says so.
Salvation is by faith alone.
We can’t earn it or keep it by works.
Where Catholics err is that they assume that just because we believe that works play no role in procuring salvation, that they are unimportant and nothing could be further from the truth.
Getting saved is the beginning of a walk with Christ which is sanctification and the goal is to become more and more Christlike as we progress. That includes obedience to God’s commands. But it doesn’t keep us saved. It keeps us growing.
And lack of works does not mean lack of, or loss of salvation. It can result, however, in the Lord’s discipline to correct us.
Contrary to Catholic thinking, when God saves us, He does not abandon us to fend for ourselves and then zap us when we screw up. He is active in the life of the believer, always. Even when that believer is not in a place of full fellowship with God because of sin.
