We have a man and wife who lead the worship in our praise and worship service who are very much into natural health and fitness. They believe that we ought to only eat like the Bible Adam and Eve were told in Genesis 1:29, vegetables and the like. I have no problem with that part of it. My problem is that they keep mentioning it in worship and use phrases like "This is how God wants all of us to eat." I have asked them 2 times to not talk about food in services. I have pointed them to Paul's statement about what we eat neither makes us superior or inferior. Well, it happened again this morning. I have an idea of what I will do, but before beginning I would like for you to weigh in. Please, I don't care to argue about food. The issue is I asked him not to mention it, but he has kept on. What should be my next step?
