one quick addendum

 since Roger asked:

I absolutely included the older son, in fact, he was much the focus of the sermon. First from the perspective of "he's in danger of being lost himself, he needs to both remember that he's not "less than" his brother just because his brother's being welcomed home but also perhaps he does need to be shown some love" (hello oldest child here). But also from the idea that some churches are struggling with two constituencies: the so-called "cradle Christians" (of which I am one - people who have been involved with the church most or all of their lives) and the newer converts/returnees/"unchurched" - the idea being, "cradle Christians" are often discombobulated by changes made to worship to make it "more welcoming" to those without a church back ground, but also that we need to hang on to some of the (good) traditions and keep them going - again, the idea of the oldest son feeling neglected and maybe put upon and the young son requiring grace. 

Like I said, there's a LOT in that parable.
