St. Bonaventure

O indescribable beauty of the most high God and purest radiance of eternal light! Life that gives all life, light that is the source of every other light, preserving in everlasting splendour the myriad flames that have shone before the throne of your divinity from the dawn of time! Eternal and inaccessible fountain, clear and sweet stream flowing from a hidden spring, unseen by mortal eye! None can fathom your depths nor survey your boundaries, none can measure your breadth, nothing can sully your purity. From you flows ‘the river which gladdens the city of God’ and makes us cry out with joy and thanksgiving in hymns of praise to you, for we know by our own experience that ‘with you is the source of life, and in your light we see light’.
