Thus their conception of the fall and of the redemption was historical. And this was a great advantage to a man of imagination inheriting their system; for the personages and the miracles that figured in their sacred histories afforded a rich subject for fancy to work upon, and for the arts to depict. The patriarchs from Adam down, the kings and prophets, the creation, Eden, the deluge, the deliverance out of Egypt, the thunders and the law of Sinai, the temple, the exile--all this and much more that fills the Bible was a rich fund, a familiar tradition living in the Church, on which Dante could draw, as he drew at the same time from the parallel classic tradition which he also inherited. To lend all these Biblical persons and incidents a philosophical dignity he had only to fit them, as the Fathers of the Church had done, into the Neoplatonic cosmology, or, as the doctors of his own time were doing, into the Aristotelian ethics. So interpreted, sacred history acquired for the philosopher a new importance besides that which it had seemed to have to Israel in exile, or to the Christian soul conscious of sin. Every episode became the symbol for some moral state or some moral principle. Every preacher in Christendom, as he repeated his homily on the gospel of the day, was invited to rear a structure of spiritual interpretations upon the literal sense of the narrative, which nevertheless he was always to hold and preserve as a foundation for the others.[2] In a world made by God for the illustration of his glory, things and events, though real, must be also symbolical; for there is intention and propriety behind them. The creation, the deluge, the incarnation, crucifixion, and resurrection of Christ, the coming of the Holy Ghost with flames of fire and the gift of tongues, were all historical facts. The Church was heir to the chosen people; it was an historic and political institution, with a destiny in this world, in which all her children should share, and for which they should fight. At the same time all those facts, were mysteries and sacraments for the private soul; they were channels for the same moral graces that were embodied in the order of the heavenly spheres, and in the types of moral life on earth. Thus the Hebrew tradition brought to Dante’s mind the consciousness of a providential history, a great earthly task,--to be transmitted from generation to generation,--and a great hope. The Greek tradition brought him natural and moral philosophy. These contributions, joined together, had made Christian theology.
