During my time at Dallas Seminary (in the early 80s) a student work up then President John Walvoord. This student told Dr. Walvoord that he had figured out who wrote the book of Hebrews. I’m not sure he said Luke, but I am sure it convinced Dr. Walvoord that some students needed more sleep!
Since there is a good chance that Luke also wrote the Epistle to the Hebrews, that makes his contribution to the NT even more impressive.
