Help me ID this book

I read this a long, long time ago. I thought that it was called ‘The Mission’ or ‘Mission’ but searches haven’t helped. Basically, Jesus comes back to Earth in the 80s and hangs out at some guys house. He actually turns water into wine and insists on experiencing everything including visiting a xxx movie house, where he proceeds to be unimpressed and says “do you think that there’s anything new under the sun” or some such pithy comment. Any takers?

The Mission by Patrick Tilley?

Thank you VERY much - couldn’t remember the author. Pearler! Merry Christmas to you.
