We cannot overestimate the damage that was done to our Gospel message when the Eastern (“Greek”) and Western (“Latin”) churches split, beginning with their mutual excommunication of each other’s patriarchs in 1054. We have not known the “one, holy, undivided” church for over a thousand years. But you and I can reopen that ancient door of faith with a key, and that key is the proper understanding of a word that many of us use often, but often too glibly. That word is Christ.
