“They won’t let me take communion!”

How should I pray for my friend who may become a missionary? What are your thoughts on the outcome of positive thinking? Do the beliefs of the “early church fathers” offer us a sound perspective on Christianity? Do I need to become an official member of my church? They won’t let me take communion until I do! Should pastors be announcing the sins of the people to the congregation as punishment? My friend showed me a video of holy laughter on YouTube, and I wonder if I’m missing something.
