Luke 24:39

Behold My hands and My feet,&c. If you cannot believe your sight, believe your touch. Let your hands prove whether your eyes have played you false. S. Augustine. For the sense of touch is more to be relied upon than the sight.

Handle me (ψηλαφήσατέ), that by touching my body you may be assured of the reality of its existence. Hence it is clear, says S. Gregory, that a glorified body is immaterial (subtile) by reason of its spiritual powers, but material (palpabile) inasmuch as it is true to its nature.

You will ask, firstly, how the glorified body of Christ could be at one and the same time material and immaterial?

I answer. First, because glorified bodies possess (1) the property of permeability, and hence are able not only to offer no resistance to another body, but even to penetrate it. And they possess (2) the power of eluding the touch, as they have the power of vanishing from the sight, according to what I have just said. These properties or powers they use or not, according as they are inclined.

Consequently, glorified bodies can be apprehended by the touch or not, according as they will.

You will ask secondly, whether this handling of Christ, His sitting at meat with the disciples, and such like, are sufficient proofs of His resurrection?

I answer that these proofs were not absolutely and physically certain, for the angels, when they appeared in bodily form, were touched and handled by Abraham, Lot, and others; but they are certain in a moral sense, and as far as human certainty permits.

1. Because on this account Christ willed to abide long with the Apostles, and to manifest Himself after His resurrection, as in His death, to their hearing, sight, and touch, senses which are held by men to be most trustworthy.

2. Because it pertained to the providence of God not to let these so great signs pass unnoticed, but to take away all pretence of deception. For the truth of the Messiah and the new religion was at stake, specially the point as to whether He really had risen from the dead.

3. Because these signs, taken in conjunction with the miracles of Christ, and the prophecies of His coming, made it both credible and certain, that He had indeed risen from the dead.
