From Bossuet’s History of the Variations of the Protestant Churches, III, 12, this gem:
For although the Eucharist, as well as the other mysteries of our salvation, had a spiritual effect for its end, it had, like the other mysteries, that which was accomplished in the body for its foundation. Jesus Christ was to be born, to die, to be spiritually risen again in the faithful ; yet he was also to be born, to die, and to rise again really, and according to the flesh. In the same manner, we were to partake spiritually of his sacrifice; yet we were also corporally to receive the flesh of his victim, and to eat of it indeed. We were to be united spiritually to the heavenly spouse ; yet his body which he gave to us in the Eucharist, in order to a mutual possession of ours, was to be the pledge and seal, as well as the foundation of this spiritual union; and this divine marriage, as well as the ordinary ones, though in a far different way, was to unite minds by uniting bodies. To speak therefore of the spiritual union was, in reality, to explain the last end of this mystery ; but to that intent, the corporal union, on which the other was grounded, ought not to have been forgotten.
