Divine providence
As the three cardinal doctrines of Judaism, Abba Mari accentuates: (1) Recognition of God's existence and of His absolute sovereignty, eternity, unity, and incorporeality, as taught in revelation, especially in the "Ten Commandments"; (2) the world's creation by Him out of nothing, as evidenced particularly by the Sabbath; (3) special Divine providence, as manifested in the Biblical miracles. In the preface, Abba Mari explains his object in collecting the correspondence; and in the treatise which follows he shows that the study of philosophy, useful in itself as a help toward the acquisition of the knowledge of God, requires great caution, lest we be misled by the Aristotelian philosophy or its false interpretation, as regards the principles of "creatio ex nihilo" and divine individual providence.
