Paragraph 1. JESUS AND ISRAEL

582
Going
even further, Jesus perfects the dietary law, so important in Jewish daily
life, by revealing its pedagogical meaning through a divine interpretation:
“Whatever goes into a man from outside cannot defile him. . . (Thus he
declared all foods clean.). . . What comes out of a man is what defiles a man.
For from within, out of the heart of man, come evil thoughts. .
.”³⁴⁶ In presenting with divine authority the definitive interpretation
of the Law, Jesus found himself confronted by certain teachers of the Law who
did not accept his interpretation of the Law, guaranteed though it was by the
divine signs that accompanied it.³⁴⁷ This was the case especially with
the sabbath laws, for he recalls, often with rabbinical arguments, that the
sabbath rest is not violated by serving God and neighbour,³⁴⁸ which his
own healings did.
