These things can also and more profitably be understood of the Church, so that they become prophetic foreshadowings of things to come. Thus Paradise is the Church, as it is called in the Canticles; the four rivers of Paradise are the four gospels; the fruit-trees the saints, and the fruit their works; the tree of life is the holy of holies, Christ; the tree of the knowledge of good and evil, the will's free choice. For if man despise the will of God, he can only destroy himself; and so he learns the difference between consecrating himself to the common good and revelling in his own. For he who loves himself is abandoned to himself, in order that, being overwhelmed with fears and sorrows, he may cry, if there be yet soul in him to feel his ills, in the words of the psalm, "My soul is cast down within me," and when chastened, may say, "Because of his strength I will wait upon Thee." These and similar allegorical interpretations may be suitably put upon Paradise without giving offence to any one, while yet we believe the strict truth of the history, confirmed by its circumstantial narrative of facts.
