Duffy - The Medieval Mass

THE LITURGY LAY AT the heart of medieval religion, and the Mass lay at the heart of the liturgy. In the Mass the redemption of the world, wrought on Good Friday once and for all, was renewed and made fruitful for all who believed. Christ himself, immolated on the altar of the cross, became present on the altar of the parish church, body, soul, and divinity, and his blood flowed once again, to nourish and renew Church and world. As kneeling congregations raised their eyes to see the Host held high above the priest's head at the sacring, they were transported to Calvary itself, and gathered not only into the passion and resurrection of Christ, but into the full sweep of salvation history as a whole.
