Reference is to Sarah Silverman.
Little known fact:
By Christian reckoning, none of Jesus' miracles--not even the raising of Lazarus or his own Resurrection--are privy to him alone as the only-begotton Son of God, the Incarnate Word, or the Messiah. Even in his working of signs, Jesus' humanity is uncompromised. It is simply a humanity which is already immersed in the Beatific Vision. Every action, miracle, and wisdom of Jesus Christ is available to us, the adopted sons and daughters and God, through the grace of faith.
There is one exception and one alone: only Christ can say "I AM"--only he can speak "with authority" in interpreting and teaching the Law, because he is literally its Author.
Jesus is Magic? In the sense that Sarah Silverman is speaking, not quite. By my understanding, it is technically incorrect to speak of the signs Christ performed as if they were his alone to perform.
