The Charism of Truth Handling: Infallibility
Jesus Christ was sent by the Father and was known as
an authentic Teacher. Forty times in the New Testament,
Christ is called "teacher" (didaskalos, also translated as
"Master"). Twelve times Christ is called "Rabbi" (master,
the address of teachers):
Matthew 23:8, 10
As for you, do not be called 'Rabbi.' You have but one
 teacher, and you are all brothers. Do not be called
'Master'; you have but one master, the Messiah.
Matthew 7:28-29
When Jesus finished these words, the crowds were
astonished at his teaching, for he taught them as one
having authority, and not as their scribes.
