http://cmcva.org/sermon-10-14-18-first-or-last/Is causing the parsing error in your feed. For some reason, it's being caused by the paragraph that contains this text "I believe there are two messages in this passage that are God’s word for Community Mennonite Church. First: divest from the economy of accumulation and give money to meet the needs of the poor. It’s a hard saying of Jesus. We have a complex economy, and how best to give is not easily answered. But if we consider that Jesus, in love, is speaking to us in our 4 materialistic emergency in order to save us, we won’t let the complexity keep us from responding to the needs of the poor."
Just looking at the text, I can't say what might be causing the parsing error. If you copied/pasted this text into the WordPress editor from an outside application such as MS Word or GDocs, it may have carried over "hidden" markup that's breaking your feed. I'd suggest completely removing this paragraph from your post, saving the post, and then retyping the paragraph manually (not copying/pasting it) and then saving the post again.
