Walter Cassels in his work, Supernatural Religion notes
As a general rule, any document so full of miraculous episodes and supernatural occurrences would, without hesitation, be characterized as fabulous and incredible, and would not, by any sober-minded reader, be for a moment accepted as historical. There is no other testimony for these miracles. Let the reader endeavour to form some conception of the nature and amount of evidence necessary to establish the truth of statements antecedently so incredible, and compare it with the testimony of this solitary and anonymous document, the character and value of which we shall now proceed more closely to examine.
it is with this background that we consider whether Luke was, first, an eyewitness to Jesus life, a companion of Paul ad the author of Acts.
As to the first point, Luke was no eyewitness. He says so himself in the first verse. HE is compiling what has come down to him from other eyewitnesses. Can his work be considered historical? I think to the extent that he writes about angels and other supernatural occurrences, that work cannot be historical.
As to whether Luke was the author of Acts, Cassels writes
After examining all the early Christian literature, and taking every passage which is referred to as indicating the use of the book, we see that there is no certain trace even of its existence till towards the
end of the second century; and, whilst the writing itself is anonymous, we find no authority but late tradition assigning it to Luke or to any other author.
And as to the final question, whether the author of Acts was a companion of Paul, the verdict, again, is negative. We cite this example, though plenty are provided for the student who wants to discover more for themselves
According to Paul himself (Gal. i. 16—18), after his conversion, he communicated not with flesh and blood, neither went up to Jerusalem to those who were apostles before him, but immediately went
away into Arabia, and returned to Damascus, and only after three years he went up to Jerusalem to visit Kephas, and abode with him fifteen days, during which visit none other of the Apostles did he see “save
James, the brother of the Lord.” If assurance of the correctness of these details were required, Paul gives it by adding (v. 20): “Now the things which I am writing to you, behold before God I lie not.”According to Acts (ix. 19—30), however, the facts are quite different. Paul immediately begins to preach in Damascus, does not visit Arabia at all, but, on the contrary, goes to Jerusalem, where, under the
protection of Barnabas (v. 26, 27), he is introduced to the Apostles, and “was with them going in and out.”According to Paul (Gal. i. 22), his face was after that unknown unto the churches of Judaea, whereas, according to Acts, not only was he “going in and out” at Jerusalem with the Apostles, but (ix. 29) preached boldly in the name of the Lord, and (Acts xxvi. 20) “in Jerusalem and throughout all the region of Judaea,” he urged to repentance.
According to Paul (Gal. ii. 1 ff.), after fourteen years he went up again to Jerusalem with Barnabas and Titus, “according to a revelation,” and “privately” communicated his Gospel “to those who seemed to be something,” as, with some irony, he calls the Apostles. In words still breathing irritation and determined
independence, Paul relates to the Galatians the particulars of that visit—how great pressure had been exerted to compel Titus, though a Greek, to be circumcised, “that they might bring us into bondage,” to
whom, “not even for an hour did we yield the required subjection.”
Given this background, where does my new friend, pastor blue jeans get his evidence for the claim that Luke was a physician, evangelist, author of acts and close companion of Paul?
