The importance of the concession that Luke was a physician should be properly appreciated. His whole gospel is written from that standpoint. For him the Saviour was the healer, the good physician who went about curing the ills of the body, while ministering to people's souls. He has more accounts of miracles of healing than any of the other Evangelists. He has taken certain of the stories of the other Evangelists who were eye-witnesses, and when they were told in naive and popular language that obscured the real condition that was present, he has retold the story from the physician's standpoint, and thus the miracle becomes clearer than ever. In one case, where Mark has a slur on physicians, Luke eliminates it. In a number of cases the correction of Mark's popular language in the description of ailments is made in terms that could not have been used except by one thoroughly versed in the Greek medical terminology of the times. As a matter of fact, there seems to be no doubt now that Luke had been, before he became an Evangelist, a practising physician in Malta of considerable experience. His testimony, then, to the miracles is particularly valuable as almost a medical eye-witness. In medical science, St. Luke's time was by no means barren of knowledge. The Alexandrian school of medicine had done some fine work in its time. It was the first university medical school in the world's history, and there dissection was first practised regularly and publicly for the sake of anatomy, and even the vivisection of criminals who were supplied by the Ptolemei for human physiology, was a part of the school curriculum. A number of important discoveries in brain anatomy are attributed to Herophilus, after whom the torcular herophili within the skull is named, and who invented the term calamus scriptorius for certain appearances in the fourth ventricle. His colleague, Erasistratus, the co-founder of this school at Alexandria, did work in pathological anatomy, and laid the foundation for serious study there. For three centuries there is some good worker, at or in connection with Alexandria, whose name is preserved for us in the history of medicine. Other Greek schools of medicine in the East, as, for instance, that of Pergamos, also did excellent work. Galen is the great representative of this school, and he came in the century after St. Luke. A physician educated in Greek medicine at that time, then, would be in an excellent position to judge critically of the miracles of healing of the Christ, and it would seem to have been providential that Luke was called for this purpose.
