First off, I am not confident in my knowledge of Mormons receiving communion so please inform me. My friend (Mormon) and I(catholic) want to go to each other's church's to experience different types of religion. We have talked for hours at the differences between each other's and we both are fascinated. I will be going with them to their church(ward?) In a few weeks and I was wondering if it would be considered disrespectful to receive communion. If so, how can I politely refuse IT? Also would it be disrespectful for them as a Mormon to receive catholic communion?
