Since they abandoned the Chinese Underground Catholics for political expediency what makes you think they care about the well being of a much small number of Russian Catholics?
Yeah, I imagine they talked about Frank's chit list of "important stuff", like making sure everyone gets 3 squares a day, making sure the elderly are cared for,
He is talking to the leader of that country, that was on his list according to what I read.
"The Vatican press office reported that Putin and Pope Francis also discussed “the critical situation faced by Christians in some regions of the world,” and spoke of questions of common interest, like “life of the Catholic community in Russia, revealing the fundamental contribution of Christianity in society.”
