I think the matter of discussing faith with a client is appropriate if that is one of the issues the client would like some help with or it is an avenue for healing. I know my t has breached the subject as one I may want to discuss but has respected that it is not at this time. So should this be a method you would like to explore I think it is totally appropeiate.

Your desire to talk about religion seems to be in a healthy manner and I think your co-workers are acting inappropriately. Good luck I know you will make a good decision.
