Asking you for chapter and verse to support your claim that Luke was no longer a doctor is me accusing Luke??
Paul says, "Luke the beloved doctor", not anything remotely like, "Luke the beloved ex-doctor."
He doesn't even say merely, "Luke the doctor" mentioning his profession as a means of identifying him, but he says, "Luke the beloved doctor", which I take as expressing his appreciation for Luke as a physician; a medical doctor. He is saying that he loved and highly esteemed Luke as a physician.
Find a better translation if you like. I believe I am taking the words in their ordinary, normal sense, and the forgoing is their plain meaning. If you have a more reasonable explanation for these words of Scripture I would like to see it.
Again, do you have any Scripture to support your claim that Luke was no longer a doctor?
Cordially,
There is zero evidence that luke used anything but the commandments of Yeshua to heal. There is also zero evidence that Paul meant anything else by his comment.
You have to remember that most of Paul’s letters were translated from Hebrew to Greek in the late second century, by people with a Gnostic agenda.
