A revolution in the attitude of Jews who believe in the unity of the Torah towards the research by biblical scholars was brought about by Rav Mordekhai Breuer who developed the "aspects approach.” The principal innovation of the approach was to acknowledge and utilize the claims of the documentary hypothesis which saw the Torah as made up of multiple and frequently contradictory texts, while maintaining that these differences and contradictions were nevertheless Divinely  authored and intended,  rather than a combination by a later editor of multiple human authors and traditions.
