1 What we have just heard and attentively received, as the holy Gospel was being read, I doubt not that all of us have also endeavored to understand, and that each of us according to his measure apprehended what he could of so great a matter as that which has been read; and while the bread of the word is laid out, no one can complain that he has tasted nothing. But again I doubt not that there is scarcely any who has understood the whole. Nevertheless, even should there be any who may sufficiently understand the words of our Lord Jesus Christ now read out of the Gospel, let him bear with our ministry, while, if possible, with His assistance, we may, by treating thereof, cause that either all or many may understand that which a few are joyful of having understood for themselves.
