Can imagine it'd be pretty hard to sue a church, as their gain is objectively trying to get people to worship Jesus. Rockstar would just get called out as the 'company trying to prevent people believing in Jesus'. I'm not a Christian or anything but it would seem like bad publicity if they do try that. Besides, at first glance I thought it was just another ad for the game, any awareness is good awareness right? One downside I can see is parents thinking the game is some Jesus worship simulator, getting it for their kids, finding out the game isn't what they thought it'd be, then complaining about Rockstar for this. Which should be liable enough for Rockstar to make them take it down.
