Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. (2 Corinthians 5:17-21)
Origen, the great biblical scholar of the 3rd Century, comments:
“Therefore, having been justified by faith, let us have peace with God through our Lord Jesus Christ… (Romans 5:1).
‘Peace’ is said where no one is in disagreement, no one quarrels, where nothing hostile and nothing barbaric is being done. So then, we who were once God’s enemies by following that enemy and tyrant, the devil, now most assuredly have peace with God, if we have thrown down the devil’s arms and have taken up the sign of Christ and the banner of his cross. But this takes place through our Lord Jesus Christ who reconciles us to God through the sacrifice of his own blood, as it is written, “When we were God’s enemies we were reconciled through the blood of his cross’ (Romans5:10, Col 1:20). Elsewhere Paul has added to those things by saying, ‘We make our appeal on Christ’s behalf: Be reconciled to God!’ (2 Corinthians 5:20). If then someone has peace with God and is reconciled through the blood of Christ, he no longer partakes of things which are hateful to God.” (COMMENTARY ON THE EPISTLE TO THE ROMANS Books 1-5, p 279)
We sing about our reconciliation with God, God forgiving our sins, each time we sing Psalm 103 as one of the Liturgy’s antiphons:
Bless the LORD, O my soul, and forget not all his benefits, who forgives all your iniquity, who heals all your diseases, who redeems your life from the Pit, who crowns you with steadfast love and mercy, who satisfies you with good as long as you live so that your youth is renewed like the eagle’s.
The LORD is merciful and gracious, slow to anger and abounding in steadfast love. He will not always chide, nor will he keep his anger for ever. He does not deal with us according to our sins, nor requite us according to our iniquities. For as the heavens are high above the earth, so great is his steadfast love toward those who fear him; as far as the east is from the west, so far does he remove our transgressions from us. (Psalm 103:2-5, 8-12)
If you, O LORD, should mark iniquities,
Lord, who could stand?
But there is forgiveness with you,
so that you may be revered. (Psalm 130:3-4)
