I Worship Thee, O my God, with all my best love and awe, with my fervent affection, with my most subdued, most resolved will. O make my heart beat with Thy heart. Purify it of all that is earthly, all that is proud and sensual, all that is hard and cruel, of all perversity, of all disorder, of all deadness. So fill it with Thee, that neither the events of the day nor the circumstances of the time may have power to ruffle it; but that in Thy love and Thy fear it may have peace—Amen.
John Henry Newman.
O God, who in Thy loving-kineness dost both begin and finish all good things; grant that as we glory in the beginnings of Thy grace, so we may rejoice in its completion; through Jesus Christ our Lord—Amen.
Leonine Sacramentary, A.D. 440.
