Yes you can. As the old priest that erynthered and I discussed the other day, he also said , God knows what you look like with no clothes on. He just wants to see you in his house talking to him. Jeans and tshirts are fine, and you can have any available seat you want, cost of admitance is free, other than your time. It's actually a pretty good deal and a decent show on occassion. Everyone should try it. Go to a few different ones though because to be honest, some are very lacking.
