Fruitless vs. Fruitful Reform

Over at Dappled Things, Don Jim has an interesting post about authentic reform, with links to various items. What caught my eye, however, was this quasi-aphorism from Fr. himself:
When reform groups begin with an attitude of criticism and agitation, rather than love for and enchantment with the Church, they take on the sour and fruitless aspect that characterizes so many of them.

This is true whether reform comes from the right or the left. It is one thing to be passionate; still another to suck the energy and joy out of everything.
