Hilary of Poitiers

Since all things are reconciled in him, recognize … that he reconciles all things to the Father in himself, which he will reconcile through himself. The same apostle says: “But all things are from God, who has reconciled us to himself through Christ and has given to us the ministry of reconciliation. For God was truly in Christ, reconciling the world to himself.” Compare the entire mystery of the evangelical faith with these words! He who is seen in him who is seen, he who works in him who works, he who speaks in him who speaks is the same one who will reconcile in him who reconciles. Accordingly, there is the reconciliation in him and through him, because the Father himself, who remains in him through the identical nature, restored the world to himself through him and in him by this reconciliation.
