This paper consists of a re-assessment of the composition of the Lukan writings in the light of the hypothesis put forward in recent years by Professor S. G. F. Brandon, Maurice Goguel and H. J. Schoeps. Briefly they claim that the church of Jewish Christians at Jerusalem actively opposed with temporary success Paul's mission proclaiming Jesus as the universal savior, that following the destruction of Jerusalem in 70 A.D. the Pauline version of Christianity emerged with new prestige while the primitive Jewish version which survived in Alexandria and, possibly to some extent in Rome, had to adjust itself to this new situation. Mark's gospel in Rome and Matthew's in Alexandria, Professor Brandon argues, are significant witnesses to this adjustment; the Lukan writings, the formation of the Corpus Paulinum, are later witnesses from the Pauline side foreshadowing early Catholicism.
