A strong Hebraic character is observable in Luke's infancy sections, quite absent from his other peculiar material. In the twenty-one verses in i, 5-25, καὶ is used many times where Luke's habit elsewhere would lead us to expect the substitution of δὲ. There are also many Hebraic phrases, such as πορευόμενοι ἐν πάσαις ταῖς ἐντολαῖς, προβεβηκότες ἐν ταῖς ἡμέραις, μέγας ἐνώπιον κυρίου, and the construction ἐγένετο, thrice used, as the formula introducing a paragraph. Luke's own hand may be seen in the introduction of δὲ three times. One of these is in connection with εἶπεν, which is probably Luke's substitute for the historic present. The retention of so many Hebraistic and non-Lucan features probably justifies Jülicher's suggestion of a special (Hebraistic, Aramaic) written source for these infancy sections. A written and not an oral source is also indicated in Luke's table of ancestors,[119] especially in its awkward placing after the baptism. It is quite impossible that Luke is here drawing upon the same source as in his great interpolation. Even more decisive in this direction than the vocabulary is the general character of the material. Sanday is "especially glad to see the stress that is laid [in certain other essays in the same volume] on the homogeneity of the peculiar matter of Luke."[120] He does not expressly say that he includes here the infancy sections, or whether he refers merely to the great interpolation; in the absence of such a statement, it may be fair to assume the former. He adds, "I fully believe, myself, in its Jewish-Christian and Palestinian origin." But when he adds further, "I can altogether go along with the view that St. Luke probably collected this material during his two years' stay at Caesarea (Acts xxiv compared with xxi and xxvii, 1); I could even quite believe with Harnack, Mr. Streeter, and Dr. Bartlet that his chief informants were Philip the evangelist and his four daughters," he is open to the suspicion of being too much influenced by a desire to trace the tradition back to a definite and authentic source, even where the data do not warrant it. There is certainly no justification for referring the infancy stories to Philip and his four daughters (and perhaps, as suggested above, Dr. Sanday does not mean to do this).
