First off, I am not confident in my knowledge of Mormons receiving communion or much of anything to do with mormonism 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
Latter-day Saints call communion "the sacrament" (realizing, of course, that it's actually just one sacrament of several). The sacrament is offered weekly and everyone stays in their pews as young boys pass trays containing first bread and then water up and down the rows. (We started using water a number of years ago when attempts were made by our enemies to poison our wine.) We don't believe in the Catholic doctrine of transubstantiation, but rather eat the bread and drink the water in remembrance of the sacrifice of our Savior. We also do it as a way of renewing the covenants we made when we were baptized, which were to take upon ourselves His name, to always remember Him and to keep His commandments. Technically speaking, the sacrament is intended for members of our Church, but if someone outside of our Church were to wish to receive it, and were to do so with the right frame of mind, I honestly don't think anyone would care in the slightest -- much less God. And in the end, it's really only His opinion that matters.
As far as your Mormon friend receiving communion at Mass, I thought a person
had to be Catholic in order to do that, and that he
had to have just recently gone to confession. I could be wrong, but I'm probably not the one to ask.
I love how you and your friend are going to go worship with each other. I had a Catholic friend as a young teenager and we used to talk a lot about the similarities and differences between our religions. Learning about one another's beliefs can only lead to greater understanding and respect for each other, and the world needs a lot more of that.
