Theophylact of Bulgaria
He desires mercy, peace, and love to be multiplied to them. Mercy, because we have been called by God and received as His servants through the compassion of His mercy. Peace, because God and the Father Himself has also granted it to us, reconciling us to Himself through His Son Jesus Christ, though we had offended Him. Love, because the only-begotten Son of God delivered Himself to death for us out of love for us.
Therefore the Apostle prays that these gifts may be abundant among the faithful, just as David cries to the Lord: "Continue Your mercy to those who know You" (Ps 35:11). Moved by these saving examples, we also, with an unfeigned disposition toward our neighbor, must live worthily of Him who called us.
