O Sacrum Convivium

Cristóbal de Morales' (c1500-1553) O Sacrum Convivium: sung by the Choir of Christ Church, Oxford, under the direction of Stephen Darlington

"What is consecration? The Word of God seizes upon some grains of baked flour and some drops of wine, sets them apart from other physical things, and fixes them in a new and holy use. It happned when Jesus blessed bread and wine at the Last Supper: it has happened in every eucharist since.
Something resembling it, though on the natural plane, happened when each of you was conceived in his mother's womb. Creative power seized suddenly upon a few elements among thousands, and fixed them in a new and vital being out of which you have come. The natural and the supernatural joined, when Christ was conceived in Mary by the Holy Ghost. The mystery is continued and extended in this holy sacrament. Bread and wine are made the body and blood of Christ; men, sluggish and blind as we are, seized by the creative Word, and confirmed in our heavenly being, as living parts of Christ." 

Austin Farrer (1904 - 1968)from ‘The Crown of the Year’ (Trinity x)
