What you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith; yet faith does not desire instruction
Recognize in this bread what hung on the cross, and in this chalice what flowed from His side... whatever was in many and varied ways announced beforehand in the sacrifices of the Old Testament pertains to this one sacrifice which is revealed in the New Testament.
Christ held Himself in His hands when He gave His Body to His disciples saying: 'This is My Body.' No one partakes of this Flesh before he has adored it.
