Cyrill of Alexandria
Though we are called children of God and of the Father, we will ultimately be subject to Him who brings us into unity with Himself, namely Christ. Consider how the blessed James, after acknowledging Ephraim and Manasseh as his children, states: ‘But thy children which shall be born of thee after them shall be thine.’ Do you grasp, then, that while we are referred to as sons of God and the Father, we ultimately belong to Christ? This aligns with what He expressed to the Father: ‘They were thine, and thou gavest them unto me:..... and I was glorified in them’ (John 17:6, 10).
