9. Eucharistic Adoration . . . He walked here in very flesh, and gave that very flesh to us to eat for our salvation; and no one eats that flesh, unless he has first worshipped: we have found out in what sense such a footstool of our Lord’s may be worshipped, and not only that we sin not in worshipping it, but that we sin in not worshipping.
