Once, while discussing Closed Communion with a skeptical LCMS member, she asked me "Do you think it PLEEEASES God?"
Having to think on my feet, I answered something like this:
"No, I don't think it pleases God that we (Christians) can't all commune together. It's a sign of our disunity and the many false teachings out there. But neither would it please God if we swept such differences under the rug, acting like they don't exist. Christians are to be loving AND truthful, and acting like there aren't important disagreements is neither truthful, nor truly loving."
