Hell, I'd be happy if the priests in my parish could preach ONE homily without benefit of reading half of it.
If a man in Holy Orders can't preach with words of power, what good is he?
Are the Protestants the only ones who teach homiletics in seminaries any more?
I'd be happy if our parochial vicar could get through one homily without taking as his text Carl Rogers or Norman Vincent Peale.
But in with my 2 cents...Part of the problem is you do not have congregations that WANT a 20/30 minute sermon. Unless things have change there were no sermons in the summer so people could "get our" in 20 minutes. Protestants (most of the:>) LIKE sermons..and they are glad to page through their bible following the points for a 1/2 hour.
I do not know how anything of substance is taught in 10 minutes..I pity the Priest that really want to teach
