O Lord, grant to us so to love Thee with all our heart, with all our mind, and all our soul, and our neighbor for Thy sake; that the grace of charity and brotherly love may dwell in us, and all envy, harshness, and may die in us; and fill our hearts with feelings of love, kindness, and compassion, so that, by constantly rejoicing in the happyness and good success of others, by sympathizing with them in their sorrows, and putting away all harsh judgments and envious thoughts, we may follow Thee, who art Thyself the true and perfect Love—Amen.

Treasury of Devotion.

Pour upon us, O Lord, the spirit of brotherly kindness and peace; so that, sprinkled with the dew of Thy benediction, we may be made glad by Thy glory and grace; through Christ our Lord—Amen.

Sarum Breviary, A.D. 1085.
