NOTE: The reception of Holy Communion, in Catholic teaching, indicates an agreement of faith, on the recipient’s part, with the Catholic doctrine of Jesus’ real presence in this sacrament. Catholics observe a Eucharistic fast of one hour prior to receiving communion. Therefore, it is inappropriate to have any food, candy, gum, etc., in your mouth while in church. Having shared in the Eucharist, you are compelled to go and work for peace and justice, thereby building God’s Kingdom now.
