1:1-3 Religion turns compliments into real expressions of respect and love. And old disciple is honourable; an old apostle and leader of disciples is more so. The letter is to a noble Christian matron, and her children; it is well that the gospel should get among such: some noble persons are called. Families are to be encouraged and directed in their love and duties at home. Those who love truth and piety in themselves, should love it in others; and the Christians loved this lady, not for her rank, but for her holiness. And where religion truly dwells, it will abide for ever. From the Divine Persons of the Godhead, the apostle craves grace, Divine favour, and good-will, the spring of all good things. It is grace indeed that any spiritual blessing should be given to sinful mortals. Mercy, free pardon, and forgiveness; for those already rich in grace, need continual forgiveness. Peace, quietness of spirit, and a clear conscience, in assured reconciliation with God, together with all outward prosperity that is really for good: these are desired in truth and love.

3. Grace be with you—One of the oldest manuscripts and several versions have "us" for you. The Greek is literally, "Grace shall be with us," that is, with both you and me. A prayer, however, is implied besides a confident affirmation.

grace … mercy … peace—"Grace" covers the sins of men; "mercy," their miseries. Grace must first do away with man's guilt before his misery can be relieved by mercy. Therefore grace stands before mercy. Peace is the result of both, and therefore stands third in order. Casting all our care on the Lord, with thanksgiving, maintains this peace.

the Lord—The oldest manuscripts and most of the oldest versions omit "the Lord." John never elsewhere uses this title in his Epistles, but "the Son of God."

in truth and love—The element or sphere in which alone grace, mercy, and peace, have place. He mentions truth in 2Jo 4; love, in 2Jo 5. Paul uses FAITH and love; for faith and truth are close akin.
