There are multiple reasons I give brief homilies. It is not for lack of preparation. In fact, it takes me more time and effort to compose a five minute homily than it would a 15 minute homily. I am reminded of what Blase Pascal once wrote, “I am sorry I wrote you such a long letter; I did not have time to write a short one.”
But there is also an implicit message I am seeking to convey by means of a short homily: the homily is not the most important part of the Mass. The Eucharist is. I want you to be filled and satisfied not by my words, but by Jesus himself.
