Here is the trailer of the film For the Bible Tells Me So. This looks like a good one for church groups to see. Thanks to Davis Community Church of Davis, CA for showing this film and for raising awareness regarding homophobia.
There are plenty of welcoming Presbyterian churches out there. Here is a good resource to find one near you.
If yours is a welcoming congregation and is not on that list, why hide your light under a bushel? Let people know that you are there! Believe me, it is worth any perceived hassle to be welcoming and to advertise it. People are looking for congregations that are welcoming and are not afraid to say it. In fact, if you can't say it, you can't claim it.
If other people who for whatever reason are prejudiced toward gays and don't like the fact that you are not, that is really their problem. Here I stand.
