I must assume all Roman Catholics are incapable of understanding anything unless it was written exactly as they required. The word 'alone' is not needed. Why do you not be honest and post all three verses which I pointed out to you? Answer. Because you know it destroys your case.
If the Scriptures can make us wise unto salvation, if they are inspired of God, if they are profitable for doctrine, reproof, correction and instruction in righteousness so that the man of God may be COMPLETE (totally what God wants him to be), completely furnished for EVERY good work, then they are all we need. (2 Tim 3.15-17)
Now compare your alternative, relying on a church stained with blood, sin, unfaithfulness, child molestation which was deliberately overlooked, dogma much of which come from its worst days, inventions of men unknown to Scripture and even contradictory to Scripture.
I think I know which I will choose. You don't make sterilised water cleaner by filling up from a tub of rainwater, much less from washing up water after washing up. I want what is pure and clean. Not ideas from a church noted for its deceit, forgeries and lies.
