No fan of Pope Francis, he sometimes shoots from the hip. I have said many times he drives me crazy. But on this point, I do think he is being misquoted and his statement when looked at deeper talks about Attraction and witness. This Pope associates Proselytism with forced or not sincere conversion. In fact, I am no fan of Proselytism myself. So the full quote is “the Church grows not through proselytism but through attraction and witness.” So Theologically, it is not a problematic statement when I looked up the entire quote.

Jorge sure is “misquoted” a lot.
