Solid on nature vs/& grace, but as with so much post-Vatican II writing, Lubac struggles to position himself just a little to the right of Hans Kung, and ends up slip-sliding down a hill he surely did not want to slip-slide down, rhetorically at least, and ends up doing too much 'it's dreadful that millions of people have been crushed by social systems, but let's not forget that they probably masturbated, and so...' As ever, we need to make sure that the important thing follows the 'but,' rather than preceding it. Of course, remember that sin and guilt are always individual, but that pales into insignificance beside the duty to help those who suffer through no fault of their own. ( )
