“My commitment to Roman Catholicism is not based on the idea that it is the true church—or that it is even the best church—but simply that it is a very important expression of historical Christianity in the West, and its reform and renewal are vital to Christian and indeed human betterment. Not that I expect that it’s going to be totally reformable according to my vision. But the reform vision of Catholicism, which has been birthed in the last 40 years, although with much deeper roots, needs to be defended as a vital option . . . even while recognizing that other views probably will remain dominant within the Church and will seek to contest and even to drive out the reform option.”
