A prayer attributed to St Columbanus
'Lord, grant me, I pray thee in the name of Jesus Christ thy Son, my God, that love which knows no fall, so that my lamp may feel the kindling touch and know no quenching, may burn for me and for others may give light. Do thou, Christ, deign to kindle our lamps, our Saviour most sweet to us, that they may shine continually in thy temple, and receive perpetual light from thee the Light perpetual, so that our darkness may be enlightened, and yet the world's darkness may be driven from us. Thus do thou enrich my lantern with the light, I pray thee, Jesus mine, so that by its light there may be disclosed to me those holy places of the holy, which hold thee the eternal priest of the eternal things, entering there in the pillars of that great temple of thine, that constantly I may see, observe, desire thee only, and loving thee only may behold, and before thee my lamp may ever shine and burn. Be it thine, I beg, most loving Saviour, to reveal thyself to us who beseech thee, so that knowing thee, we may love thee only, love thee alone, hold thee in our thoughts; and do thou deign so far to inspire us with thy love, as it befits thee to be loved and cherished as our God; that thy charity may possess all our inward parts, and thy love may own us all, and thine affection may fill all our senses, so that we may know no other love apart from thee who art eternal; that such affection may be in us impossible of quenching by the many waters of this air and land and sea, according to that saying "And many waters are not able to quench love", which in us also can be fulfilled even in part, by the gift of thee our Lord Jesus Christ, to whom is the glory unto ages of ages. Amen'.
