I usually don't do this, but I must poke fun at a fellow St. Blog's parish site which has spent the last week defending an adjective in its blog name as if it were homoousia. This is the kind of thing that makes the Orthodox laugh at us.
Update: Whoa, didn't know Amy Welborn had expounded on the matter. I still think "intentionality" is inextricably chained to a voluntaristic model of human agency, more congruent with Protestantism than apostolic Catholicism. If intentionality is what Catholics lack, we're not going to find it by aiming to be more "intentional."
