Hello to you!
I am a bit new to these forums, as this is my first post.
Please forgive me my naivety, but I have been under the impression that Luke wrote both his gospel and Acts as a two part volume. I do not read any languages other than english so I am strictly going by an english translation.
From what I can see, using Murdock's translation, I see in Luke 1:1-4:
01 SINCE many have been disposed to write narratives of those events, of which we have full assurance,
02 as they delivered them to us, who from the first were eye-witnesses and ministers of the word;
03
it seemed proper for me also, as I had examined them all accurately,
to write out the whole, methodically,
for thee, excellent Theophilus:
04 that thou mayest know the truth of the statements, which thou hast been taught.
And from the book of Acts 1:1-2:
01
THE former book have I written, O Theophilus concerning all the things which our Lord Jesus Messiah began to do and teach,
02 until the day when he was taken up, after he had instructed those legates whom he had chosen by the Holy Spirit.
Now again, I do not speak/read/write languages other than english, so I am no "scholar" but I am simply taking the text at face value. Also using a translation of the Peshitta/Peshitto (I do believe in Aramaic primacy) and the books of Luke and Acts are not being called into question as genuine as far as I am aware. In my
opinion I see no reason to think Acts was written by anyone other than Luke.
Edit:
I decided to look up alternate theories and sure enough I found one: Did Luke the Physician write the Book of ACTS?

Is this what you are referring to? From the authors article, he suggests that Titus is the author, if not AN author of Acts. Is this perhaps what you are referring to?
I refuse to be too dogmatic about this and am interested in what other info you may have and what others here seem to think.
