Prayed the office of readings for the first time in some time today, and was treated to a great patristic reading. A highlight was "he tongue is released because a voice is being born – for when John was already heralding the Lord, he was asked, Who are you and he replied I am the voice of one crying in the wilderness. John is the voice, but the Lord in the beginning was the Word. John is a voice for a time, but Christ is the eternal Word from the beginning."
But the bit I want to write here to remember it myself is this. I have proposed some matters for inquiry, and listed in advance some things that need to be discussed. I have introduced these points even if we are not up to examining all the twists and turns of such a great mystery, either for lack of capacity or for lack of time. You will be taught much better by the one who speaks in you even when I am not here; the one about whom you think loving thoughts, the one whom you have taken into your hearts and whose temple you have become.
From Augustine's sermon for the Nativity of John the baptist, I just thought it was a good method for catechisis to keep in mind for those times I find myself giving a talk or session.
