Union with Christ

Early Christian writers used the Latin phrase, unio cum Christo, meaning "union with Christ." Although the New Testament does not use such a phrase, Paul does tell the Corinthians that "the one who is joined to the Lord is one spirit with Him" (I Cor. 6:17). Early Greek Christian writers often referred to our "participation in Christ," even using the word theosis to explain such union. It is important that Christians of our day understand what "union with Christ" really means.
