Fiancé wants communion at wedding, i don't.

I am unsure of the Episcopal church, but in the Catholic church Holy Matrimony is viewed as a sacrament that can also be taken in conjunction with Reconciliation and Eucharist, two other sacraments. Many practicing individuals choose this and perhaps in a similar vein, that is how your future spouse envisions their wedding day. I did the first two and not communion as my husband had not yet converted. We do plan on renewing vows with communion as we want to fully experience this part of our faith.

I would ask your church for the specific ceremony schedule. In the catholic mass, vows, exchange of rings, and proclamation of marriage happens before communion, so the marriage ceremony itself is not interrupted. Physicially, the couple is moved to the side where they can pray while wedding guests come up to take communion which is viewed as both a personal and communal experience. To conclude the day, the officiant often says something nice about the couple before they walk down the aisle to applause. The purpose of the ceremony is not forgotten.

I know you mentioned your sacrifice in having a church ceremony, but I do think when one half of the couple feels very strongly about their wedding ceremony itself, logistics and efficiency are lacking excuses. You might find the church will take a more considerable place in your future afterall. In my church, I find myself praying for (strength, patience, compassion in my) marriage every week.

Will the church be able to do communion for both of you after the guests have left? You will need to be ready to accommodate his religious practices in many more situations after getting married. So, keep that in consideration. Try to figure out compatible paths for your marriage.
