your Question was “There were people and groups in N-W EUrope that did not know of the See of Rome”. I have proven you wrong. Do you retract your earlier, incorrect statement?
” I have proven you wrong.”
You haven’t PROVEN anything; you’ve only delivered the “SEE”s mail for them. Just because you say to me, “You are incorrect,” doesn’t make you correct.
The “SEE” does not want any believers to show up in NW Europe before its priests get there, but that does not mean they weren’t there.
