The Feast of the Epiphany of Our Lord Jesus Christ is one of the oldest Christian feasts, though, throughout the centuries, it has celebrated a variety of things. Epiphany comes from a Greek verb meaning "to reveal," and all of the various events celebrated by the Feast of the Epiphany are revelations of Christ to man. http://catholicism.about.com/od/holydaysandholidays/p/Epiphany.htm
