I have a friend who is a traditional Catholic like myself but goes to the extreme sides with the SSPX Resistance and groups like them.
He doesn’t like the Divine Mercy devotion because it was rejected by according to him three Pope’s.
It was actually two Pope’s and was poorly translated.
He also rejects it because Sr Faustina grabbed the host and this is prior to the changes in America and a few other countries where they legalized an illegal disobedience of communion in the hand.
He ask my why Sr Faustina didn’t know about the Fatima children.
The last question he ask me I think is kinda dumb because the message is overall the same and course she wouldn’t know about the three Fatima children she lived in Poland as a cloistered nun.
