We, therefore, are taught, through the slight want of faith shown by the blessed Thomas, that the mystery of the Resurrection is effected upon our earthly bodies, and in Christ as the firstfruits of the race. He was no phantom or ghost, fashioned in human shape, and simulating the features of humanity, nor yet, as others have foolishly surmised, a spiritual body that is compounded of a subtle and ethereal substance different from the flesh. For some attach this meaning to the expression “spiritual body”. For since all our expectation and the significance of our irrefutable faith, after the confession of the Holy and Consubstantial Trinity, centres in the mystery concerning the flesh, the blessed Evangelist has very pertinently put this saying of Thomas side by side with the summary of what preceded. For observe that Thomas does not desire simply to see the Lord, but looks for the marks of the nails, that is, the wounds upon His Body. For he affirmed that then, indeed, he would believe and agree with the rest that Christ had indeed risen again, and risen again in the flesh. For that which is dead may rightly be said to return to life, and the Resurrection surely was concerned with that which was subject unto death
