The theology of a theologian worthy of the name cannot be anything but the very movement of his mind and love as he seeks the truth about God in the teaching of sacred scripture and in the study of his creatures. Such is the theology of St.Thomas Aquinas. Some of the propositions (in which theology is expressed) are set forth here for meditation. Their choice is entirely my own. The writer who reports them has never been able to reread them without having the impression of their leading him as close to God as is possible for a human mind to approach him while meditating on the meaning of his word. My only desire is to share that experience with others. It will never be a question of demonstrating, but only of showing, leaving to each reader the task of finding his own way and trying in his own fashion to approach the sublime mysteries whose neglect would be the death of metaphysics as well as of theology, and whose meditation, in the humility of love, is a work of piety no less than of wisdom.
