Another "What was that book" question

I read a book many years ago and I’ve been trying to find it but no luck. I don’t remember the title or the author, here is what I think I remember (no guarantees) of the plot:

The main character has just been released from many years in prison (now he’s a priest?) and is traveling back to the planet where he ran into trouble many years ago. On that planet, once every X years something happens that causes people’s reality to be very distorted for 12 or 24 hours or something. If I remember right the guy is going back to see if he can make it through this strange effect without running around and killing people (like he did last time?).

Does any of that sound familiar?

Thanks! I’ve been googling for a long, with no luck.
