When I was a teen we had a priest come to our parish who had groupies, and when he was moved to another parish a number of people left our parish to attend church at his new one. I mean there are always some priests who are more popular and all have their set of firm supporters but this was way beyond that.
He had a very distinct style and manner and there was a great deal of fawning and also controversy around him. He was also the youth group leader and had a crowd of teens that literally followed him around and sang his praises.
I found it an uncomfortable situation, and not my style, but I don’t know that anyone was at fault, but I know it caused a great deal of tension in the parish and in the area and lots of strong words were said on both sides of the issue.
