Now, I think there's an argument could be made for retaining the Holy Kiss. Our church does. Our church is an Anabaptist church where I attend, and we retain the Holy Kiss. Not everybody greets with the Holy Kiss. I normally don't greet someone unless I know they're a member of our church or I know that they are comfortable with being greeted with a kiss. If they're just a visitor that I don't know, I don't greet someone, not because I think it's going to defile me, but because it's going to embarrass them.
They're going to feel very uncomfortable because it's not something they're used to. So I tend to only practice it among other Christians who are used to it, who would want to be greeted that way. Join us in earnestly contending for the faith that was once for all delivered to the saints.
