Not sure where you are going with this. But, Luther had more than 17 years of marinating in Roman error...until God rescued him from their heresies. It took a long time to work out the errors still stuck in his thinking. Many never did get worked out. His view of baptism, the wine/bread/, even some politics came and went. I am not advocating Luther, Calvin, Hus, Zwingli, or even Sproul. They all have contributions and they all have limitations. But, at least they point at the Book as the proof text for truth.
The Book is our source doc for truth and Rome does not comport with the Book they wrongly claim to have delivered to the world. They are driven by tradition and they point at themselves as the source of truth. Therein lies the problem.
What I am saying is to be aware of what the evangelical pitch (which I accept as true and have proven out in practice, which by the way is what the bible tells us to do) will look like on the Roman end. They’re going to view it through a heavy cloud of presuppositions which is why we get objections like “oh, you’re being your own pope.” That’s where “patient instruction” means more than what might look like a temper tantrum to them.
I hope I’m not talking past you. I’m just saying the evangelical model has nothing to be ashamed of if the bible is not only preached but obeyed in presenting it. The two (doctrine and obedience) really are integrated wonderfully by the Holy Spirit.
Basically... present the bible with your life. Not just your talk. That’s all I’m getting at. It’s a love affair with God that you want to spread.
