Why don’t you familiarize yourself with the Waldenses and the Albigenses? That would be a good place for you to start. God has always had a faithful witness outside of Rome. However, despite all her apostasy and wickedness through the centuries, it was Trent where Rome actually declared in writing her apostasy. At Trent she anathematized believers in the gospel of Jesus Christ in an official way. Before that they weren’t teaching the gospel, but I don’t believe they had ever declared it accursed in a official way.
“God has always had a faithful witness outside of Rome”
And your church is just magically connected with whomever was ‘not Rome’ at any particular time?
That’s awfully, ‘convenient’ I must say.
15 hundred years and you claim succession from whomever was ‘not Rome’.
You know what that smells like to me? Prejudice. A mystical barrier that separates ‘Catholic’ from ‘Christian’.
