Some people are really gifted in what I'll call "ministering" to hurting folks. Their faith is an asset to them in this, and the overall message you can read in their actions is that they accurately perceive and respond to a need, in an approriate way. The idea is, "I have something that might be helpful to you and I'd like to offer it."
Some, however, are more gifted in "outreach" and "witnessing," and the message you ultimately get from their behavior is that you need to join them, believe as they do, and so forth. The idea is, "I have something you need and I am going to give it to you."
At our church, we're careful about this distinction. Our liturgy and leadership reflect vast amounts of detached patience, a down to earth view of life, and a pervasive sense of the universe's ultimate wellbeing. So folks in a world of hurt, when they come in the door, find a sense of peace and tranquility that can do a lot for them. They stay as long as that meets their need. Sometimes they make a commitment to stay; sometimes they move on. We don't think it's up to us to judge what makes sense for them, about that. If they need to be somewhere else, we figure they are doing the right thing, and we're happy about that, for them.
For instance one minister we knew casually was having a horrible struggle with his congregation, and he also was so overworked that these two factors were burning him out, fast. He left his position to recover and rethink. He and his wife started coming to our place just to have a safe place to sit and pray and not be expected to do or give anything in return. He and my husband met for some long talks, the kind you have around a campfire. And we prayed for them a lot.
This is how we ARE-- it was not a special boon for a colleague. Eventually they decided to join our denomination officially and ceremonially. But we'd have loved them just as much if they had moved on.
THAT's the kind of atmosphere you want to be on the lookout for. IMO. It's OK to go see if this place has that, and it's OK to trust your gut about it if you do go.
