I thought this particular portion of a rather long article was quite 'on topic' - and I'm interested in seeing the comments about this person's words:
"Jesus and the Old Testament
Let us now try to draw together what Jesus took from the Old Testament and what, therefore, Christians may hold to be of permanent validity.
First, Jesus shared with Old Testament thought the general structure of God-centered moral living. It apparently never occurred to him to give ethical injunctions derived from any other source. A great deal of our contemporary problem about "love perfectionism" centers in the attempt to ground ethics either in human nature or in the structure of social institutions. The biblical view — both Old Testament and New — makes obedience to the will of God the final criterion of the good life.
Did Jesus accept the idea of the covenant, and with it of Israel as God’s chosen people? This question is crucial for the universality of his message. Apparently, at the beginning of his ministry he conceived his mission as to the "lost sheep of the house of Israel." It was to this group and not to the Gentiles that he commissioned the twelve (Matt. 10:5-6), and his encounter with the Canaanite woman (Matt. 15:21-28) is significant in the fact that he both at first demurred and then yielded to her entreaty for the healing of her daughter. This gives the key to Jesus’ attitude. His own people were precious to him, and he never expressly repudiated the covenant relation. Yet to him so universal was the love of God, so compelling the need to serve every human being, that the covenant with its exclusive bounds was left behind. It remained for his followers in the early Church to make concrete the break which his acts and attitudes foreshadowed.
Second, his ethical principles were those of Judaism, yet with a difference in emphasis which makes their impact new. Point for point, there is nothing in the teaching of Jesus which cannot be found in the Old Testament or in the rabbinical teaching. Pharisaism, though it had its faults which called forth Jesus’ rebuke, had also in it much that was great and good. Witness, for example, this passage from The Testaments of the Twelve Patriarchs, written toward the end of the second century B.C.:
Love ye one another from the heart; and if a man sin against thee, speak peaceably to him, and in thy soul hold not guile; and if he repent and confess, forgive him. But if he deny it, do not get into a passion with him, lest catching the poison from thee he take to swearing and so thou sin doubly. . . [But] if he be shameless and persist in his wrong-doing, even so forgive him from the heart, and leave to God the avenging....."
