I've been going to a PCA church for a few months now, and I've been glad to have been going there, but I'm starting to have a problem with something. I really feel that wine should be used in Communion instead of grape juice, but the church uses grape juice. I'm not actually a member of the church, but I'm not sure what I should do. The reason that it is being used is because some of the people who are members there used to have alcohol problems.
