Bernard of Clairvaux, Monastic and Theologian, 1153
The Collect:
O God, by whose grace your servant Bernard of Clairvaux, kindled with the flame of your love, became a burning and a shining light in your Church: Grant that we also may be aflame with the spirit of love and discipline and walk before you as children of light; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.
