The New Christian Covenant and the Mosaic Law

The new Christian covenant differs from the Mosaic Law in that its content has not been made explicitly clear by God as a set of commands. Instead, it needs to be interpreted from the teachings of Jesus and the apostles. 2 Timothy 3:16-17 tells us, “All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work.” It is also significantly different in that the demands it makes are individual for each and every one of us, whereas much of the old law, and the punishments inflicted for people’s transgressions, were “corporate” in nature, involving a body of people, although, as Moo states, “the individual Israelite could, it seems, be cut off from the covenant for flagrant disregard of the law of God.”[1]
Willem VanGemeren says, “Under the new covenant, the law can never again be read, interpreted, or applied apart from Jesus Christ. He modeled the perfection of the law and simplified it. The ceremonial laws, civil laws, and the penal code have been abrogated, and the moral law has received further clarification in the person and teaching of Jesus Christ.”[2]
When Jesus said, of the first two commandments, “on these two commandments hang all the law and the prophets,” (Matthew 22:40) He positioned “love” as the major emphasis of the new covenant, and it is this quality that brings forward a “simplified” version of the moral law into the Christian age. Believers are also tasked with communicating the Word of God to others. Bahnsen reminds us that, “At the very time that Christ claimed all authority upon earth, he simultaneously indicated that the nations still needed to be made his disciples.”[3] Matthew 5:19 teaches that we must both obey the law and teach it correctly.
Fortunately, for weak and sinful man, assistance is now available by means of the power of the Holy Spirit, through which, says VanGemeren, “the believer desires to know and to do the will of the Father.[4]
The Application of the Mosaic Law to the Life of the Christian.
There is agreement between several commentators that the authority of the Mosaic law ended with the advent of Jesus’ ministry on Earth. This is confirmed by the changes in the commandment relating to the Sabbath, and since it is shown that the law needs to be interpreted as a whole, rather than in parts, the failure of this one part brings down the authority of the whole. But while the ceremonial and civil commands, designed to support the worship, lifestyle, and legal needs of the Jewish nation 2,000 years ago, are not now applicable to the present-day Christian, the moral content of the law lives on through its expression within the new covenant. Through Jesus, mankind now has direct and personal contact with God in a new covenant, which, while different from the old, can be regarded as a further stage of the same eternal plan.
Moo neatly summarizes the new covenant when he states that the whole of the original Mosaic law is fulfilled by Christ, which means that it is no longer applicable to God’s people, and in its place, he says, is “the law of Christ,” which comprises the “teaching and example of Jesus and the apostles, the central demand of love, and the guiding influence of the indwelling Holy Spirit.[5]
The emergence of love as the main plank of the new Christian covenant means that, with the exception of the fourth commandment relating to the Sabbath, we are still beholden to the Ten Commandments of the Mosaic law, not because they are still laws, but instead because they are the natural consequences of our love for God, and, by natural extension of this, of our love for our fellow man. Strickland introduces Paul’s point, in Romans 6:12-14, that “believers in Christ do not need to let sin reign over them. Sanctified Christians must avoid sin (v. 13) and not be mastered by it (v. 14).”[6]
The Holy Spirit Transforms, Illuminates and Guides
VanGemeren supplies a word of gratitude for the assistance God provides, for each and every one of us, in complying with the new covenant, “Thanks be to God that the Holy Spirit transforms individuals, who love God, but are looking for guidance apart from the whole Bible. Through his illumination and guidance, he brings them to a point where they sweetly comply with the moral law, and thus submit themselves to the Father’s will.”[7]

Becoming a true Christian means that you have come to believe that Jesus Christ is your Lord and Savior. This is a process that, for me, took several years of reading Christian books, going to bible studies, and finding and attending the right church. I remember feeling a little envious of those who appear to be “saved” instantly when attending a Billy Graham meeting or going forward for an altar call. Could it, or should it, really be that easy? Why did it take me about four years of investigation before I even began to feel comfortable as a Christian? I now realize that it is a lifelong journey. Fifteen years and an MA in Christian Apologetics later, I am still learning, and the more I learn, the more I discover I still need to learn, and want to learn.
