What does 'church' mean when it has the head in heaven and the body on earth?
It means the Ecclesia, the called-out assembly, whose Head is Christ in heaven and whose body is on earth, yet inseparably joined. Ephesians calls it His body, the fullness or complement of Him, pictured in marriage. This church cannot be separated from its Head.
Les explains that this is still the word Ecclesia, a called-out assembly, but with one difference: this church has its head in heaven while the body is on earth, and the two cannot be separated. In Ephesians 1:22-23, God gave Christ to be Head over all things to the church, which is His body, the fullness of Him that filleth all in all. The word fullness in the Greek also means complement, so we are the complement of the Head. Les compares this to Genesis, where Eve was given to Adam as his complement and became part of him, and to Ephesians 5, where the physical marriage relationship pictures Christ and the church which is His body. He notes that Peter does not mention the body of Christ.
