Therefore, my dear friends, flee from idolatry. 15 I speak to sensible people; judge for yourselves what I say. 16 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? 17 Because there is one loaf, we, who are many, are one body, for we all share the one loaf. (I Corinthians 10:14-17)
Today in western Christianity, pagan rituals are sometimes considered “cute” “ethnic” or “harmless.” (And example of this, for instance, might be the baking and eating of Mexican “dead bread” for Halloween). But it is still not appropriate for Christians to participate in these rituals, because we never know who is watching and if they believe that these rites truly involve communion with supernatural spirits. We who are Christians have communion with God. We celebrate our union with Him, and Christ’s death on the cross, every time we take the bread and the wine. It is not fitting for those of us who are members of God’s universal church to also participate in rituals that show allegiance to pagan deities, even if we don’t believe in those deities ourselves.
