A number of recent works have attempted to deal with the theological thought of the evangelist Matthew using the method of ‘Redaktionsgeschichte’. But as yet Hans Conzelmann's Matthew has not appeared. Certainly the joint work of G. Bornkamm, G. Barth and H. J. Held, the works of R. Hummel, G. Strecker, K. Stendahl, W. Trilling and others have contributed considerably to this field of study. But at the present time there is no agreement among scholars on the fundamental problem of what is the essential concern of Matthean theology. It is true that the Law of Moses and accordingly the problem of the fulfilment of Old Testament prophecies is one of the most important problems for Matthew, and that the present state of the church and the expectation of the eschaton, especially of the last judgement, are also elements indispensable for understanding the thoughts of the evangelist. But the fundamental problem is how to discover the basis of Matthew's theology, by means of which the interpreter can understand these individual elements as organically combined.
