What are the identifying marks of Jesus?

Answer 1

If your asking for the ONLY sign Jesus gave that He was the Messiah, the Anointed One of God, then this is the answer:

Matthew 12:38-42New King James Version (NKJV)

The Scribes and Pharisees Ask for a Sign

38 Then some of the scribes and Pharisees answered, saying, "Teacher, we want to see a sign from You."

39 But He answered and said to them, "An evil and adulterous generation seeks after a sign, and no sign will be given to it except the sign of the prophet Jonah. 40 For as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth. 41 The men of Nineveh will rise up in the judgment with this generation and condemn it, because they repented at the preaching of Jonah; and indeed a greater than Jonah is here. 42 The queen of the South will rise up in the judgment with this generation and condemn it, for she came from the ends of the earth to hear the wisdom of Solomon; and indeed a greater than Solomon is here.

Answer 2

several may be the marks in his hands, where the nails would have been driven through. And perhaps white robes, but I'm not catholic, so I wouldn't know.
