This verse is central to the debate over the relationship between the New Testament and the Old Testament first begun by Marcion of Sinope. There are several parts of the New Testament where Jesus can be read as rejecting some tenets of Mosaic law. Issues include the traditional understanding of the Sabbath in, divorce laws in, and dietary prohibitions in. The antinomian viewpoint holds that, because Jesus accomplished all that was required by the law, thus fulfilling it, he made it unnecessary for anyone to do anything further. Proponents of this view believe this view was described by the Apostles in Acts of the Apostles, and that the Jewish Christians overlooked such teaching as they continued to worship in Herod's Temple as prescribed by the Mosaic Law, even after the resurrection. According to this view, anyone accepting his gift of salvation would not only avoid consequences of failing to live up to the law, but is no longer expected to do any works of the law for any spiritual reason. The opposite of antinomianism, is that the entire Torah Law is still entirely applicable to Christians; not for salvation, but rather for simple obedience. This interpretation stems primarily from the New Testament affirmation that Jesus Christ was sinless in every way, sin is defined by the Torah, and that Jesus' followers, both Jew and Gentile, are admonished to imitate Him in every way. This view affirms the six points of St. Augustine listed above, but differs from other traditional views by affirming obedience to specific commands of the Law such as dietary laws; laws to which other views teach obedience is no longer intended by God. Proponents of this view see and as evidence that Jesus did not negate any aspects of the Biblical Torah Law for his followers. Furthermore, they see it as a contradiction of Jesus' sinlessness for Him to have taught disobedience to any Torah command, no matter how small. For references for this view, see Christian views on the old covenant.
Early Christians
This issue was a central one to the Jewish Christians, that the author of Matthew is widely believed to have been a part of, as the Jewish Christians would have accused the Pauline Christians of abandoning Jewish doctrine, for example the Council of Jerusalem and Acts of the Apostles : Some scholars also believe that antinomianism, the belief that all was allowed because there were no laws, was believed by a faction in the early Christian community. In this verse the Gospel of Matthew directly counters these views by insisting the old laws such as the Ten Commandments are still valid. France notes that "law and prophets" was a common expression for the entirety of what Christians today call the Old Testament, though it more correctly refers to the Mosaic Law and Neviim, see Biblical Canon. The main controversy over this verse is over the word "fulfill." What exactly does fulfilling the laws entail? A wide number of reading of the word plerosai, fulfil, have been advanced. Among them are: establish, confirm, validate, complete, bring into actuality by doing, set forth in their true meaning, accomplish, and obey. These varying definitions and the textual uncertainty over the status of the law have led to a number of understandings of the relationship between Mosaic law and the New Testament. In the early church there were a number of factions that felt the coming of Jesus had brought about a rejection of the Old Testament, these included the followers of Simon Magus, Marcionism, Gnosticism, Montanism, Manichaeism, and others. The Ante-Nicene Fathers in the early church rejected these views and spent considerable time rebutting them. For example, Irenaeus rejected Marcion and praised the Apostles in his Against Heresies 3.12.12:
St Augustine
Another important writer who rejected any break between Jesus and Moses was St. Augustine who outlines his view in his Reply to Faustus, a Manichaeist. Augustine outlined six different ways in which Jesus fulfilled the law:
He explained the true meaning behind the rituals and ceremonies
He gave additional commands that furthered the intentions of the Law.
Other writers
The most important of these arguments was the sixth, that Jesus expanded the law but did not replace it. A number of others used analogy to explain this notion. Chrysostom used the analogy of a race saying that Jesus had added extra distance for the Christians to run, but the beginning remained the same. Theophylact of Bulgaria used the image of an artist colouring in an outline, and St. Thomas Aquinas saw it as how a tree still contains the seed. This view became the accepted Roman Catholic position, but was challenged in the Protestant reformation. Leading Protestants such as Martin Luther, John Calvin, and Huldrych Zwingli rejected the idea Jesus had added to the Law. Rather they argued that Jesus only illustrated the true Law that had always existed, but had been badly understood by the Pharisees and other Jewish leaders. The Anabaptists took the opposite view and felt the Jesus had greatly reformed the Law and felt that Old Testament precepts could only be justified if they had been reaffirmed by Jesus. E. P. Sanders in Jesus and Judaism, published in 1985, argued that Jesus was a Pharisee, as he could find no substantial points of opposition. Jesus himself did not transgress any part of the Mosaic law, did not oppose or reject the law, and that the disciples continued to keep it, as is shown by their continued worship in Herod's Temple. Sanders also argued that Jesus' sayings did not entirely determine early Christian behaviour and attitude, as is shown by Paul's discussion of divorce, where he quotes Jesus' sayings and then gives his own independent rules..
