Q. 1. My friend is marrying a non-Catholic. Their wedding shall take place at a Catholic Church. Can her spouse to be, who is non-Catholic, receive Holy Communion on this special occasion?
A. 1. The teaching of the Catholic Church is that non-Catholics cannot receive Holy Communion during the Holy Mass, not even at one's wedding. Receiving the Eucharist is a sign of complete unity among believers and the full acceptance of Catholic teachings. Catholics and non-Catholics do not share this special unity.
When a non-Catholic Christian will be involved in a Catholic wedding, because of his/her inability to receive Holy Communion, it is often the practice not to have a Holy Mass as part of the nuptial liturgy.
