[Ali Imran]

Allah also paraphrased Jesus's words...one eg " the first and the last" does that mean that the Quran is corrupted

Instead of responding to the argument, you brought a non-sequitur.

Why don't you tell me why one or both of the authors of that two Gospels changed the words of Jesus?

The change is significant. In Mark, Jesus denies being God. And then, later in Matthew, they changed the words where Jesus denies being God.
