Friday of the 20th week in ordinary time

From the discourse of St Ambrose on Psalm 48

The one mediator of God and men is the man Christ Jesus

‘Brother does not redeem; a man shall redeem; he shall not give to God his ransom, nor the price of the redemption of his soul’; that is, ‘Why shall I fear in the evil day?’ For what can hurt me, who not only do not need a redeemer, but am myself the redeemer of all? I shall make others free, and shall I be afraid for myself? See, I make all things new, surpassing the affection and duty of kinship. The one whom a brother, delivered into the light of day from the same mother’s womb, cannot redeem, because he is held by the weakness of an equal nature, him will a man redeem: the man, however, of whom it was written that the Lord ‘will send them a man who will save them’; one who said of himself: ‘You seek to kill me, a man who has spoken the truth to you.’

  But although he is a man, who shall know him? Why shall no one know him? Because just as there is one God, so also there is one mediator of God and men, the man Christ Jesus. He is the only one who will redeem man, surpassing kinsfolk in duty; because he sheds his own blood for strangers, whereas a brother cannot do this for a brother. And so to redeem us from sin he did not spare his own body; and he gave himself a ransom for all, as his true witness the apostle Paul affirmed, who claimed: ‘I tell the truth, I do not lie.’

  But why is only this man the redeemer? Because no one can equal him in goodness, insofar as he lays down his life for his own servants; no one can equal him in innocence, for all are under the yoke of sin, all lie under Adam’s fall. Alone he is chosen as redeemer since he cannot be affected by the ancient sin. Therefore, by ‘man’ let us understand the Lord Jesus, who assumed the state of man, to crucify the sin of all in his own flesh, and by his own blood wipe out the condemnation of all.

  You may perhaps say: ‘How is a brother denied the possibility of redeeming, when he himself said, “I will proclaim your name to my brothers”?’ But it was not as brother to us, but as the man Christ Jesus, in whom was God, that he did away with our sins. So it is written: ‘God was in Christ, reconciling the world to himself, in that Christ Jesus of whom alone it was said that the Word was made flesh and dwelt among us. So it was not as a brother but as Lord that he dwelt among us when he dwelt in the flesh.
