For example, it takes uncommon mendacity to profess salvation by faith alone when James 2:20-26 forcefully condemns it.
Veneration of relics, as well as the doctrine of Purgatory are wholly scriptural (Acts 19:12, 1 Cor. 3:11-15).
I see mendacity is your new favorite word.
Your cherry-picking and over emphasis of some verses of Scripture show that you don’t even begin to have a basic grasp of the major thrust of the teachings of Paul in Galatians and Romans, nor of the overall emphasis of the New Testament. In other words, you don’t understand the gospel.
Perhaps you should take a course in hermeneutics, learn about principles of interpretation, and how to keep things in context. And, if you have already done so, PAY ATTENTION THIS TIME.
Your current posture is exactly what I would expect from someone steeped in, and unable to see beyond, Roman Catholic dogma and tradition (regardless of what facts, history, and the Bible testify).
Also, your characterization of Luther shows a gross disregard for anything remotely approaching historical accuracy or fairness.
