Wilfred L. Knox (1886–1950) was a theologian and fellow of Pembroke College, Cambridge. Volume I of his Sources of the Synoptic Gospels was published posthumously in 1953. The gospels were written to preach Christ and not to satisfy the curiosities of the modern scholar; but they do contain important historical material of the first importance. That is Dr Knox's contention: and these volumes seek to take Gospel criticism a stage beyond Form-criticism. The result of many years' work, this volume focuses on the Gospel of St Mark, whilst the 1957 Volume II is concerned with St Luke and St Matthew. Following Knox's death. The manuscripts for both of these volumes were edited by the Rev. Henry Chadwick and published in their present form.
