Incense kicks off people's asthma (among them, my husband.) Recovering alcoholics would like grape juice instead of wine for the Eucharist. Others need gluten-free wafers for the host. Me, I have OCD, and as I have said before, using the common cup for the Eucharist, for me, is liking kissing everyone in church on the mouth. Fortunately, our church allows dipping the host in the cup. I see the arguments for a common cup, but I personally wouldn't mind individual being an option, because of my own frailties. Obviously things that affect health are more important than OCD.
Where am I going with this? Just thinking how many things are happening in the life of the church that St. Paul and Luther and probably even Walther would never have dreamed of. I wonder what kind of human idiosyncrasies affected the church in their days?
