At most we had about 3 different religious types in our 'group', who regularly same to Stoned-Henge (my mate's flat) for a few blasts. Surprisingly we had a Sikh lad and a Muslim lad, as well as a 'Shinto' lad (he was from Japan) and as you can imagine, it was a sheer conflict of faith, haha. The Muslim guy, Sadiq I think his name was, would dramatically fetch his Quran and start preaching to the Sikh guy whose name could have been Balvinder (long time ago), and the Sikh guy would be totally Zen and just puff away at him.
I had a few really insightful conversations with the Japanese lad, and I always remember his name cos it was almost the same as the creator of Metal Gear Solid, Hideo Komatsu it was. Shinto is a bit scary as a religion, though, to be honest. Bit dark and mysterious, so we often had to shush him cos it's doctrines would send us paranoid.
