Dear still_waters, What evidence do YOU have that St. Luke the Physician and Evangelist did NOT write the Gospel of St. Luke? Do you just accept on faith that Luke did not write the Gospel of Luke? If he didn't, then who did?
In Erie PA Scott R. Harrington PS Why would anyone even begin to doubt that Matthew wrote Matthew, Mark wrote Mark, Luke wrote Luke and Acts, John wrote John, 1,2,3 John, and Revelation, James wrote James, Jude wrote Jude, Peter wrote 1,2 Peter, and Paul wrote all the rest of the NT?
It's stupid to doubt the authorship of any book of the Bible, and, if we don't know the exact author, we know the Inspirer is God, which is really all we need to know in any case.
We just need to believe the 76 books of the Bible are the written Word of God.
