So if he now believes that the catholic church is the one true church does he feel that he has to answer for people that he “led astray” as a Protestant?
I must say that, on the whole, if you’re going to pick a Protestant denomination, Foursquare is a good place to be. It is firm in its moral teachings, and with its focus on living for Jesus, a person will inevitably grow closer and more like Jesus the longer he attends.Converts to Catholicism don't get filled with hate for the groups they leave behind.
Why don't you ask him? Mind-reading of third parties may be technically permitted on this forum, but it's still a bad idea.
I am reminded of a conversion story I read a few years ago. IIRC, the fellow was Baptist. Among other things, he recounted having looked up many folks he "witnessed to" in his previous faith, and having explained to them why he now thought his previous testimony to them was wrong. He had been a Mormon. I may disagree with his present theology, but I admire his persistence and intellectual honesty. I can't say that I've ever read/heard about anyone else, of any religious persuasion, doing that.
