As Christians we hold the Bible to be the Word of God. We acknowledge the Scriptures are ultimately God’s idea, and that he inspired the human authors to write them for the good of those who read them (2 Pet 1:20 -21). We rightly acknowledge the Bible to be the ultimate authority for the Christian life. But this poses something of a challenge: How do we rightly interpret the Bible within a modern-day setting when it was not written by or to people in the modern day? How do we take these ancient words of authoritative revelation and apply them well to contemporary situations? As our society changes and seems increasingly keen to let go of Christian mores, this becomes an ever more pressing issue.
One of the particular challenges we face in this regard is the way we bring the laws of the Old Testament to bear on the church and society today. As we read the Pentateuch (the first five books of the Bible), we encounter laws about various aspects of life, and we often appeal to these in discussions about Christian behaviour and the ethics of society at large. We recount the Ten Commandments in our liturgy as a statement of God’s righteous standards. We hold some laws as binding today (e.g. not murdering), but relinquish others (e.g. prohibitions against eating certain foods). This can create a serious dilemma, because on the surface, it looks like an arbitrary approach—a purely selective retention of those laws that suit us, and the rejection of those that don t. Indeed, this is how many caricature our handling of Scripture. Unfortunately, in many cases, they are right. We have not thought carefully enough about interpreting Old Testament laws to ensure that we do not do so arbitrarily. We must do justice to these laws as integral parts of God’s authoritative word to us, and that means having a rationale for how we interpret them.
One method popularly espoused is to divide the Law into three categories: (1) civil laws pertaining to the life of Israel as a national entity in ancient times; (2) ceremonial laws pertaining to how Israel worshipped God at the tabernacle or temple; and (3) moral laws that indicate the ethical standards God desires of people. Under this scheme, the civil and ceremonial laws are seen as no longer applicable to Christians, because they are fulfilled in Christ. The moral laws, though, do continue to have force, since God’s standards have not changed. It therefore takes Jesus fulfilment of the Old Testament and the high ethical standards of believers quite seriously.
There are a few problems with this approach, however. First, the Law itself does not make this kind of threefold distinction. The laws together constitute a singular whole. While we are still permitted to divide it up for the purposes of analysis, it becomes easy to take these divisions as absolute features of the Law, rather than useful tools. It’s a bit like treating a three-room house like three distinct houses. Second, the New Testament sees Jesus as the fulfilment of the Law in its entirety, not just two portions of it. And third, the Law is an all-or-nothing proposition. Paul’s interaction with the Gentile believers in Galatia demonstrates this. When the Judaizers came to Galatia and urged the Gentile believers to undergo circumcision in order to be part of the people of God, Paul reacted strongly. He told the Galatians that if they wanted to be characterised by observing the Law, they had to keep all the laws, not just portions of them (Gal 5:3). But this would be to no avail anyway, since no one can ultimately be justified through the Law (Gal 3:11). Nevertheless, Paul also affirms that when Christians walk in step with the Spirit who has been given to them (Gal 5:16, 25) and love their neighbours as themselves, they fulfil the entire Law—not just part of it (Gal 5:24). Carving the Law up into applicable and non-applicable slices simply does not do it justice.
So how should we approach the Law as Christians? The answer to that question would take many more pages than this article allows. Nevertheless, here are some principles and ideas that are vital stakes in the ground when considering the place of the Law today.
Types of Laws
It’s useful to understand the nature of the laws we read in the Bible. There are two broad types of laws. The first are apodictic laws, which plainly state what people must or must not do. The Ten Commandments (Deut 5:6 -21) are the best examples of these. The second type are casuistic laws. These don t hand down a do or a do not . Rather, they describe hypothetical cases and dispense advice on how these cases could be handled. From these cases, readers can derive principles that can be applied in other scenarios. This is important to realise, because casuistic laws are not exhaustive. They do not explore all the possible alternative situations that people might encounter. They are simply worked examples. It is easy to think that casuistic laws are simplistic, unjust, or have numerous loopholes. But this is to treat them as apodictic laws, or misunderstand them as exhaustive. Their hypothetical nature also means that understanding the ancient culture that provided the context for these laws is also invaluable. Without that context, it can be easy to misconstrue the intent of these laws.
The Old Covenant
God gave his laws to his ancient people, Israel. These laws were part of his old covenant, by which he established a particular kind of relationship: God was Israel’s head of state , and they were his national society within the land he gave them. The old covenant was about establishing and maintaining a nation, which is why laws were appropriate for ordering the covenant relationship. This is very different to our situation as Christians today. Jesus has established a new covenant in which we relate to God not as citizens towards a head of state, but as children towards a heavenly Father. We have become a family, which is why Christians relate to each other not merely as neighbours , but as brothers and sisters . While our relationships to God and each other still require order to function well, laws are actually an inappropriate means for this. A family that needs laws imposed on its relationships is not functioning in a healthy way. A family functions well when its members share an inherent identity that inextricably binds them to each other in love. Affection, more than duty, is what makes a family function well. A nation, however, requires a dutiful level of order. Understanding the different dynamics required in running a family and a nation gives us some leverage for understanding the rationale of some of the Old Testament laws, and how they may relate to us today.
The Purpose of the Law
The Law was not about saving a person unto eternal life. Rather, it was about enabling a person to be a good citizen of old covenant Israel within the land. The Apostle Paul, for example, could boast about being blameless with regards to the righteousness that comes from the Law (Phil 3:6). But this type of righteousness only allowed him to be a good Hebrew of Hebrews —a citizen of Israel, but not necessarily a citizen of heaven. This is why he counted such credentials loss for the sake of knowing Christ and having the righteousness that comes through faith in him (Phil 3:9). This is a new type of righteousness, which is apart from the Law, though the Law (and the prophets) testified to it (Rom 3:21). Only Christ is able to save unto eternal life. Christians are not under the old covenant, so we are not required to live as a national entity within a particular land. We are, instead, under the new covenant, which allows us to relate to God as our Father, regardless of our ethnicity. This means we must not impose the Old Testament Law on Christians today. It is not necessary for salvation or Christian identity. Only Christ is necessary for salvation.
Other cultures of the ancient Near East had law codes. The Code of Hammurabi from Babylon (c. 1750 bc) is one of the best known of these. Some laws in these codes bear a striking resemblance to those found in the Old Testament. The law of retaliation is an example, whereby proportionate punishment is given for a crime: eye for eye, and tooth for tooth (cf. Exod 21:23 -25). However, there are also some glaring differences. For example, Hammurabi’s code stipulates that no one must harbour an escaped slave, but must immediately return the slave to his master. On this front, however, God’s Law is profoundly countercultural. It stipulates that if an animal escapes from its owner, the person who finds it must do all in their power to return the animal (Deut 22:1 -3). But if a slave escapes from his master, Israelites must not return the slave to his master, but allow him to live among them (Deut 23:15 -16). In other words, the Law does not see slaves as property, but as human beings with an inherent right to personal freedom. This is why Israel was only ever to see slavery as a temporary measure for settling debts (Deut 15:12 -15). When we consider the ancient world’s view of slaves as dispensable chattels, God’s Law is countercultural. It sows the seeds of compassion and dignity that would eventually inspire the likes of William Wilberforce to bring the institution of slavery to an end. The Law outlines Israel’s duties, but at its heart is love of neighbour. This should be a guiding principle in how we analyse it.
This countercultural aspect of the Law is not just about Israel being different to other nations for the sake of being different. As we ve seen, Israel shared some laws in common with its neighbours. Rather, it is about establishing practices and policies that reflect the justice, righteousness, and love of God. The Law aims to treat people as persons in relationship with others. This is not the same as treating people individualistically—as singular units without reference to others. It is about promoting personhood and relational wellbeing. This is why it bids the powerful of society to use their power in loving service of the weak, usually characterised as the fatherless, the widow, and the migrant (e.g. Deut 10:18). In an ancient society that lacked many of the social and political infrastructures that we enjoy in the West today, this was a crucial message.
Same God, Different Context
The God who gave Israel the Law is the same God who has spoken and acted in Jesus Christ. We worship the same deity whom old covenant Israel worshipped (or, rather, should have worshipped). But while God himself has not changed, our understanding of God is, in fact, different to the understanding Israel had. In Old Testament times, God was still in the process of revealing himself. This is why he kept sending prophets to Israel, and why Israel had to keep adapting to this unfolding revelation. We, however, live after the completion of God’s revelation in Christ. The Law was not God’s final word—Christ was. Failing to take Christ into account is like interrupting God mid-sentence, and not letting him speak. It can be presumptuous and lead to misunderstanding.
So as we interpret the Old Testament Law, we must appreciate the difference in historical and theological context between Israel and ourselves. We must feel the difference between bc and ad . Yet we must also recognise that God has not changed. This means we should be able to see a consistency between the Law given to Israel and what God requires of us today, but this consistency is situated in the character of God, not in the laws themselves. Although we (technically) no longer have the institution of slavery, the laws on slavery should still speak to us of a God who values human dignity and freedom, and which places people above economics. And while we are in a different salvation-historical context to old covenant Israel, there are some things that have not changed. For example, human nature is still the same. Our capacity for sin, our biological composition, and our personal limitations are unchanged. While our context may be different to old covenant Israel’s, our need for God and his revelation has not.
The change in historical and theological context demonstrates that the Law is not a timeless revelation. It was, rather, a revelation in history. Paul describes the Law as Israel’s tutor, put in place until Israel’s time of maturity and fulfilment arrived—the time of Christ (Gal 4:1 -7). The Law is, therefore, not binding on Christians today as Law. But this does not mean the authority of God’s Law has expired. The Law remains the word of God as it ever was, for it still speaks to us of the God we worship, and of our forebears in the people of God. But it speaks to us today as prophecy and wisdom, rather than as Law. It testifies to the God whom we know today as our Father. It testifies to his righteousness, justice, and love. It provides us with the framework for understanding God’s dealings with his people in ages past, and in so doing, still provides us with wisdom on what is pleasing to God. The Law is like a tall tree whose shadow has moved through the day. It now casts a different shadow on a different landscape, but it is the same tree as it was in the morning. As such, we can affirm the truth of Paul’s words to Timothy when it comes to the Law: All Scripture is breathed by God and is useful for teaching, rebuking, correcting, and training in righteousness, so that the person of God may be complete, equipped for every good work (2 Tim 3:16 -17).
