And our fourth, last Christian Stage shall be represented by St. Thomas Aquinas (A.D. 1225-74), in the one great question where this Norman-Italian Friar Noble, a soul apparently so largely derivative and abstractive, is more complete and balanced, and penetrates to the specific genius of Christianity more deeply, than Saints Paul and Augustine with all their greater directness and intensity. We saw how the deepest originality of our Lord's teaching and temper consisted in His non-rigoristic earnestness, in His non-Gnostic detachment from things temporal and spatial. The absorbing expectation of the Second Coming, indeed the old, largely effete Graeco-Roman world, had first to go, the great Germanic migrations had to be fully completed, the first Crusades had to pass, before--some twelve centuries after Nazareth and Calvary--Christianity attained in Aquinas a systematic and promptly authoritative expression of this its root-peculiarity and power. No one has put the point better than Professor E. Troeltsch: 'The decisive point here is the conception, peculiar to the Middle Ages, of what is Christian as Supernatural, or rather the full elaboration of the consequences involved in the conception of the Supernatural. The Supernatural is now recognized not only in the great complicated miracle of man's redemption from out of the world corrupted by original sin. But the Supernatural now unfolds itself as an autonomous principle of a logical, religious and ethical kind. The creature, even the perfect creature, is only Natural--is possessed of only natural laws and ends; God alone is Supernatural. Hence the essence of Christian Supernaturalism consists in the elevation of the creature, above this creature's co-natural limitations, to God's own Supernature'. The distinction is no longer, as in the Ancient Church, between two kinds (respectively perfect and relative) of the one sole Natural Law; the distinction here is between Natural Law in general and Supernature generally. 'The Decalogue, in strictness, is not yet the Christian Ethic. "Biblical" now means revealed, but not necessarily Christian; for the Bible represents, according to Aquinas, a process of development which moves through universal history and possesses various stages. The Decalogue is indeed present in the legislation of Christ, but as a stage preliminary to the specifically Christian Ethic. The formula, on the contrary, for the specifically Christian Moral Law is here the Augustinian definition of the love of God as the highest and absolute, the entirely simple, Moral end--an end which contains the demand of the love of God in the stricter sense (self-sanctification, self-denial, contemplation) and the demand of the love of our neighbour (the active relating of all to God, the active interrelating of all in God, and the most penetrating, mutual self-sacrifice for God). This Ethic, a mystical interpretation of the Evangelical Preaching, forms indeed a strong
