1 May the Lord our God be present, that He may grant us to render you what we promised. For yesterday, if you remember, holy brethren, when the shortness of the time prevented us from completing the sermon we had begun, we put off until today the unfolding, by God's assistance, of those things which are mystically put in hidden meanings in this fact of the Gospel lesson. We need not, therefore, now stay any longer to commend the miracle of God. For He is the same God who, throughout the whole creation, works miracles every day, which become lightly esteemed by men, not because of the ease with which they are wrought, but by reason of their constant recurrence.
Those uncommon works, however, which were done by the same Lord— that is, by the Word for us made flesh— occasioned greater astonishment to men, not because they are greater than those which He daily performs in the creation, but because these which happen every day are accomplished as it were in the course of nature; but the others appear exhibited to the eyes of men, wrought by the efficacy of a power, as it were, immediately present. We said, as you remember, one dead man rose again, people were amazed, while no man wonders at the birth every day of those who were not in being.
In like manner, who does not wonder at water turned into wine, although God is doing this every year in vines? But since all the works which the Lord Jesus did, serve not only to rouse our hearts by their miraculous character, but also to edify our hearts in the doctrine of faith, it behooves us thoroughly to examine into the meaning and significance of those works. For the consideration of the meaning of all these things we deferred, as you remember, till today.
