Gen 11:27-32 : The question arises, therefore, whether the angel of Jehovah, or of God, was God Himself in one particular phase of His self-manifestation, or a created angel of whom God made use as the organ of His self-revelation.
(Note: In the old Jewish synagogue the Angel of Jehovah was regarded as the Shechinah, the indwelling of God in the world, i.e., the only Mediator between God and the world, who bears in the Jewish theology the name Metatron. The early Church regarded Him as the Logos, the second person of the Deity; and only a few of the fathers, such as Augustine and Jerome, thought of a created angel (vid., Hengstenberg, Christol. vol. 3, app.). This view was adopted by many Romish theologians, by the Socinians, Arminians, and others, and has been defended recently by Hoffmann, whom Delitzsch, Kurtz, and others follow. But the opinion of the early Church has been vindicated most thoroughly by Hengstenberg in his Christology.)
