Sermons/homilies definitely make a difference to me. Even among Catholic churches, I would drive further if the homilies are better at one. Yet location does matter to me somewhat too simply as a matter of convenience for me and my vehicle. The nearest Catholic parish to me is a half mi. It is considered my geographical parish. But I would definitely drive 5 miles to another. I’ve driven 7 miles to one. Due to the priest(s), the atmosphere, the homilies and so forth. I’d drive further if need be.
This is really fantastic. I would like to salute you for your seriousness, and enthusiasm in following the mass.

In all my life, I have never met a Catholic who would do this – to drive the extra mile just because there is a good speaker celebrating the mass.
In fact on the contrary is true. There are parishioners who fulfill their Sunday obligation by going to the next parish because their own parish priest always gave unusually very long homily. They need the time for some errands.
In fact the homily is based on the three readings, which the parishioners should already read the night before the mass, though admittedly not many do that. They know the content and for fifteen minutes of the homily, nothing much can be summarized from the passages of the readings. Perhaps this is the reason why most Catholics do not really bother with the quality of the homily knowing it to be something factual. Of course, it would be wonderful if the priest is funny and can make you laugh. Otherwise, probably much that was said in the homily, very few people remember.
So homily is just a part of the mass. You spend too long on it, then the mass would last longer. In a big congregation, something between one to one and quarter hour long mass would be just nice. Anything longer than that would cause practical problem, like parking for the next mass and people would start becoming fidgety.
For really good comprehensive preaching and teaching, Catholics would not get that from the mass though of course there is no denying its value, but for the former they would go for seminars, retreats and those prayer gathering like the prayer meetings where preaching is the ‘main event’.
The recent trend of priesthood training however, has taken cognizance of the weakness of priest homilies. Those young priests that I talked to were telling us that they learned public speaking in the seminary. Wow, so they see the need for selling and marketing as well.
