This overview of de Lubac's work considers his background in French Catholicism at the opening of the twentieth century; the intellectual currents a-swirl in his formative years; his own education in Jesuit institutions; the mosaic of his highly disparate writings, and the broad lines of his ‘career’ as priest and cardinal. This ‘panorama’ is complemented by a proposal, intended to illuminate the ‘mosaic’ referred to: the author's suggestion is that unity – in a variety of analogical senses of that word – constitutes the key to de Lubac's entire enterprise.’
