A church recently split and the new mission that was formed recently asked me to preach for them for a while. They then asked me to perform the Lord's Supper for them. I did without hesitation...this resulted in one preacher friend telling me I had insulted God since I hadn't been a member of their church and another close friend saying it was open communion and borderline ecumenicalism. The mission is Baptist and, as a Baptist, I expressed it would be more close communion. Was I wrong?
