I think there’s a principle that says if a point or message can’t be made in 6-8 minutes, it won’t be made in 15 minutes either. I have also noticed some distinct cultural differences in homilies from foreign visiting priests. Young priests from Africa and especially Poland seem to give “homilies” that come across as long scolding sessions. Priests from India seem to give longish but quite gentle teachings. Visiting Irish priests - who are always older - are wonderful to listen to are are usually quite loving and often funny.
I’ll agree in general, but there are specific points that need more time to be drawn out. Take a different discipline, for example mathematics, as an analogy. Principles of mathematics build on each other. You don’t start on day one learning about derivatives. First, you have to learn how to count. Second, you need to learn how to add and subtract. Then multiply and divide. Then fractions, decimals, exponents, and algebra. Eventually, you get to geometry and pre-calculus. Then, finally, you are ready for calculus.
Take this over to the realm of preaching. I often times will read, here and elsewhere, something along these lines, “Why don’t we ever hear any homilies on why you shouldn’t receive communion in a state of mortal sin?” The answer, to be perfectly blunt, is because people’s attention span isn’t long enough to handle a homily to properly lay out this point. (Now, that said, I have preached on this before.)
It’s not as simple as going up and saying, “Remember, folks, the Church teaches that you shouldn’t receive Holy Communion if you’re not in a state of grace,” and being done with it.
Off the top of my head, you need to adequately explain AT LEAST the following points (keeping in mind that people are at different points…someone may be setting foot inside a Catholic Church for the first time in years, for instance).
*]What is mortal sin?
*]What does it mean to be in a state of grace?
*]What is the Eucharist?
*]Why shouldn’t we receive Holy Communion when NOT in a state of grace?
*]What might constitute a mortal sin?
*]What are the consequences of mortal sin?
*]What are the remedies for it? (The LAST thing you want to do as a preacher is leave someone in a state of despair)
*]Address the objection, "So, you’re saying I’m not WORTHY to receive Holy Communion? How dare you judge me! Haven’t you ever heard Jesus say, “Judge not?”
Again, these are just off the top of my head. In general, the more controversial the topic, the more time you need to give a good catechesis on it.
Yes, long preaching can be a problem. But, only preaching half a message due to having a self-imposed seven minute time limit is a bigger problem, in my estimation. Personally, I’ve preached homilies that were two words long and homilies that were 20 minutes long. It all depends on the topic. Obviously, the 20 minute homily had more that needed to be fleshed out for it to make sense. I’d say my average is about 7-10 minutes, but I do think it’s problematic when we limit ourselves by that.
