You said: What arrogance.
Testimony to the Truth of Jesus Christ is never arrogant, although many reject it.
It depends on whose truth it is. I know we agree on some facets of truth and disagree on extra biblical stuff. If only we’d stick to what scripture says about it all. Sigh.
It’s your assumption that only Catholics know the truth and protestants are, well, uneducated, etc., that’s arrogant.
