In context, in Matthew 15:1-9, Jesus is giving the Pharisees as good as he's getting from them, pointing at the very thing in their own lives of which they were accusing his disciples. But the heart of Christ's criticism of the Pharisees was that they honored God with their lips but their hearts were far from Him (vs. 8). Were the Pharisees, then, in constant, open contravention of the Mosaic law? No, they were so keen to live under law that they'd made some of their own! They wouldn't have been regarded by their fellow Jews as the religious leaders of their time if they'd been grossly neglectful of the laws of God. It was the very duplicitousness of their lives - obeying God and appearing to have a heart for Him, but actually having no love for Him whatever - that made them the hypocrites Jesus said they were.
This same duplicity exists in many believers today, who seek to show they love God by their "Christian living," when, in their hearts, they are far from Him, desiring many other things much more than they do Him.
In any case, your objection to my reference to Christ's words doesn't negate what Paul wrote concerning love.
Jesus showed the utmost respect for the Torah and for those to whom it granted genuine authority. (
Matthew 5:17-20; Luke 5:14; 17:14) But he frequently denounced those who overstepped the commandments of God. (
Matthew 15:3-9; 23:2-28) Such men followed traditions that came to be known as the oral law. Jesus rejected its authority. In turn, many rejected him as the Messiah. They believed that only someone supporting the traditions of those in authority among them could have God’s backing.
You know as I do the Israelites came into a covenant relationship with YHWH God at Mount Sinai in 1513 B.C.E. Through Moses, they received the statutes of that covenant. (
Exodus 24:3) Following these regulations would allow them to ‘prove themselves holy as YHWH their God was holy.’ (
Leviticus 11:44) Under the Law covenant, worship of YHWH God involved sacrifices offered by a designated priesthood. There was to be a central place of worship which as you know eventually became the temple in Jerusalem.(
Deuteronomy 12:5-7; 2 Chronicles 6:4-6)
So as do I, you know the Mosaic Law provided the overall structure for Israel’s worship of YHWH God as a nation. However, some details were not explicitly stated. For instance, the Law forbade work on the Sabbath, but it did not draw an explicit line between work and other activities.(
Exodus 20:10)
If YHWH God had seen fit to do so, he could have provided detailed regulations covering every conceivable question. But he had created humans with a conscience, and he allowed them the initiative to serve him with a degree of flexibility within the framework of his statutes. The Law made provision for judicial cases to be dealt with by priests, Levites, and judges. (
Deuteronomy 17:8-11) As cases increased, certain precedents were set, and no doubt some of these were passed on from generation to generation. Methods of caring for the priestly duties at Jehovah’s temple were also conveyed from father to son. As the nation’s collective experience increased, so did its traditions.
At the heart of Israel’s worship, however, remained the written Law given to Moses. So you know what
Exodus 24:3, 4 states: “Moses came and related to the people all the words of Jehovah and all the judicial decisions, and all the people answered with one voice and said: ‘All the words that Jehovah has spoken we are willing to do. Accordingly Moses wrote down all the words of YHWH." It was in keeping with these written commandments that God concluded his covenant with the Israelites. (
Exodus 34:27) So in fact, the Scriptures nowhere mention the existence of an oral law.
The Mosaic Law clearly left primary religious authority and instruction in the hands of the priests, the descendants of Aaron. (
Leviticus 10:8-11; Deuteronomy 24:8; 2 Chronicles 26:16-20; Malachi 2:7) Through the centuries, however, some priests became unfaithful and corrupt. (
1 Samuel 2:12-17, 22-29; Jeremiah 5:31; Malachi 2:8, 9) During the era of Greek domination, many priests compromised on religious issues. In the second century B.C.E., the Pharisees, a new group within Judaism that distrusted the priesthood, began instituting traditions by which the common man could consider himself as holy as the priest. These traditions appealed to many, but they were an unacceptable addition to the Law.(
Deuteronomy 4:2; 12:32)
The Pharisees became the new scholars of the Law, doing the job that they felt the priests were not doing. Since the Mosaic Law did not allow for their authority, they developed new methods of interpreting Scripture through cryptic allusions and by other methods seemingly supporting their views. As the chief caretakers and promoters of these traditions, they created a new base of authority in Israel. By the first century C.E., the Pharisees had become a dominant force in Judaism.
As they collected existing oral traditions and searched for Scriptural implication to establish more of their own, the Pharisees saw the need to give added authority to their activity. A new concept regarding the origin of these traditions was born. The rabbis began to teach: “Moses received Torah at Sinai and handed it on to Joshua, Joshua to elders, and elders to prophets. And prophets handed it on to the men of the great assembly.”(Avot 1:1, the Mishnah)
In saying, “Moses received Torah,” the rabbis were referring not only to the written laws but to all their oral traditions. They claimed that these traditions, invented and developed by men, were given to Moses by God at Sinai. And they taught that God had not left it up to men to fill in the gaps but had orally defined what the written Law had left unsaid. According to them, Moses passed this oral law down through the generations, not to the priests, but to other leaders. The Pharisees themselves claimed to be the natural inheritors of this “unbroken” chain of authority. Because Jesus condemned the oral law which were actually traditions of men the Pharisees as an organization would never accept Jesus as the Messiah because the Pharisees believed the Messiah would have to accept their oral law if he truly was the Messiah.
You can believe that the Pharisees were obedient to the law covenant when Jesus himself shows they cared more about their tradition or oral law than the law covenant. The Pharisees often opposed Jesus regarding Sabbath observance, traditions, and association with sinners and tax collectors. (
Matthew 9:11; Mark 7:5; Luke 6:2)
"The nature of the difference [between Jesus and the Pharisees] is made clear only in the light of the two opposing understandings of God. For the Pharisees, God is primarily one who makes demands; for Jesus he is gracious and compassionate. The Pharisee does not, of course, deny God’s goodness and love, but for him these were expressed in the gift of the Torah [Law] and in the possibility of fulfilling what is there demanded. . . . Adherence to the oral tradition, with its rules for interpreting the law, was seen by the Pharisee as the way to the fulfilment of the Torah. . . . Jesus’ elevation of the double command of love (
Matt. 22:34-40) to the level of a norm of interpretation and his rejection of the binding nature of the oral tradition . . . led him into conflict with Pharisaic casuistry.”
