1 Corinthians 3:23 - Ellicott's Commentary On The Whole Bible

And Christ is God’s. — Probably these words were added, not only as being the great climax of the gradual ascent up which the Apostle’s thoughts and language have gone in the whole passage, but as avoiding any danger of the party who called themselves by the name of Christ, arrogating anything to themselves from the previous words, “Ye are Christ’s,” if the passage had concluded with them. Christ is God’s as being Mediator (as John 14:28; John 17:3.) There was no danger, in that early age of the Church, of these words being misunderstood (as some have endeavoured to misunderstand them since) as in the least implying a want of absolute identity between the Son, in regard of His Divine Nature, and the Father.
