Is it possible that Thomas as described in the Gospel of John chapter 20 is a doctor? The reason for this is because of verse 5. Thomas demands to see the mark of the nails in his hands, and put his finger in the mark of the nails and his hand in his side. If Thomas was a medical doctor it would explain his response in verse 28, "My Lord and My God" after examining wounds that he knows are not survivable?
I am trying to establish if there is any correlation between the named apostles in John chapter 21 and the pseudonyms used for the authors of the gospels. For example, Eusibeus/Papias states that John Mark was the interpreter and scribe for Simon Peter, we know that the son of Zebedee (John) according to tradition wrote the Gospel of John, but what about the other two... Nathaniel aka Bartholemew appears to be a Jew which would fit with the author of Matthew but what about Thomas? Was he working with a follower of Paul aka Luke to form the Gospel of Luke?
