Our word epiphany comes from a Greek word meaning "manifestation or appearance," and in church history this word has become closely associated with the revelation of Christ in connection with the visit of the Magi. Epiphany has been observed throughout much of the Western church as occurring on January 6.
Often the content of our Christmas celebration is shaped by what we do with the weeks following Christmas. Churches that observe Christmas as a standalone event may find it difficult to get past the sentimentality of seeing a cute, mild-mannered baby in the manger. But the incarnation involves much more than the drama of Christmas itself; it brings a vision of God's glory to the nations of the world.
