Sursum Corda points to this excellent essay by Stanley Hauerwas, who echoes Alisdair MacIntyre in basing ethics upon submission to a discipline of life.
When Hauerwas says that "to learn to pray requires that we learn to pray with other Christians. It means we must learn the disciplines necessary to worship God." I fear that American Catholicism seems to have failed to provide such spiritual exercises. Perhaps there was no greater communal prayer than the exercise, that is, the askesis, of the Friday fast so hurriedly abolished after Vatican II. Besides Sunday Mass, how many Catholics actually pray together?
