CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 590–593

590 Only the divine identity of Jesus' person can justify so absolute a claim as "He who is not with me is against me"; and his saying that there was in him "something greater than Jonah,. . . greater than Solomon", something "greater than the Temple"; his reminder that David had called the Messiah his Lord, and his affirmations, "Before Abraham was, I AM", and even "I and the Father are one."
591 Jesus asked the religious authorities of Jerusalem to believe in him because of the Father's works which he accomplished. But such an act of faith must go through a mysterious death to self, for a new "birth from above" under the influence of divine grace. Such a demand for conversion in the face of so surprising a fulfillment of the promises allows one to understand the Sanhedrin's tragic misunderstanding of Jesus: they judged that he deserved the death sentence as a blasphemer. The members of the Sanhedrin were thus acting at the same time out of "ignorance" and the "hardness" of their "unbelief".
592 Jesus did not abolish the Law of Sinai, but rather fulfilled it (cf. Mt 5:17-19) with such perfection (cf. Jn 8:46) that he revealed its ultimate meaning (cf.: Mt 5:33) and redeemed the transgressions against it (cf. Heb 9:15).
593 Jesus venerated the Temple by going up to it for the Jewish feasts of pilgrimage, and with a jealous love he loved this dwelling of God among men. The Temple prefigures his own mystery. When he announces its destruction, it is as a manifestation of his own execution and of the entry into a new age in the history of salvation, when his Body would be the definitive Temple.
