Contradiction with Matthew 27:5
Luke 6:16 identifies Judas Iscariot as a traitor, yet Matthew 27:5 shows his remorse and end by hanging, indicating repentance rather than persistent betrayal.
Matthew 27:5: And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.
Contradiction with John 6:70-71
While Luke 6:16 calls Judas a traitor, John 6:70-71 notes that Jesus had chosen Judas, implying divine purpose and involvement, which complicates the portrayal of Judas as merely a betrayer.
John 6:70-71: Jesus answered them, Have not I chosen you twelve, and one of you is a devil?
Contradiction with Acts 1:18
Luke 6:16 describes Judas as a traitor, but Acts 1:18 depicts his demise and the acquisition of a field as his possession, showing how his betrayal led to unintended consequences, seemingly beyond mere traitorous intent.
Acts 1:18: Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.
