This thesis is a study in the Christology of Alexander of Hales. I chose Alexander as a subject simply because I wanted to become acquainted with a theology not of my own tradition and there is no better period to choose for this purpose than the thirteenth century, the century of the scholastic giants. Having chosen the period the next question to be asked was "who could I study besides Thomas Aquinas"? The fact that there were good new texts available of Alexander's main works and the fact that he was a man of some stature in his own day together with the fact that most Protestants have never heard of him seemed a good reason to discover the source of his great reputation. There were problems about the text of the Summa in that there were doubts as to its genuineness but I hoped that these problems would be solved as I proceeded. However, this was not to be so. Because of the doubts about the genuineness of the Summa this thesis has become a study in the Christology of Alexander which appears in the Glossa on the Sentences of Peter Lombard. Together with this there are discussions of the views of the Quaestiones at the end of each topic in this thesis.
