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.
