Are Christians Inconsistent with Old Testament Laws?

One of the main arguments used against Christians is that we are inconsistent with upholding all of the Old Testament Laws. Many Christians are not sure how to answer such a statement and end up leaving the conversation feeling defeated and confused.

Dr. Tim Keller helps better equip Christians as to how to answer this question in his post, “Making Sense of Scriptures’s ‘Inconsistency.'”

Keller writes:

I find it frustrating when I read or hear columnists, pundits, or journalists dismiss Christians as inconsistent because “they pick and choose which of the rules in the Bible to obey.” Most often I hear, “Christians ignore lots of Old Testament texts—about not eating raw meat or pork or shellfish, not executing people for breaking the Sabbath, not wearing garments woven with two kinds of material and so on. Then they condemn homosexuality. Aren’t you just picking and choosing what you want to believe from the Bible?”

I don’t expect everyone to understand that the whole Bible is about Jesus and God’s plan to redeem his people, but I vainly hope that one day someone will access their common sense (or at least talk to an informed theological adviser) before leveling the charge of inconsistency.

First, it’s not only the Old Testament that has proscriptions about homosexuality. The New Testament has plenty to say about it as well. Even Jesus says, in his discussion of divorce in Matthew 19:3-12, that the original design of God was for one man and one woman to be united as one flesh, and failing that (v. 12), persons should abstain from marriage and sex.

However, let’s get back to considering the larger issue of inconsistency regarding things mentioned in the Old Testament no longer practiced by the New Testament people of God. Most Christians don’t know what to say when confronted about this issue. Here’s a short course on the relationship of the Old Testament to the New Testament.

The Old Testament devotes a good amount of space to describing the various sacrifices offered in the tabernacle (and later temple) to atone for sin so that worshipers could approach a holy God. There was also a complex set of rules for ceremonial purity and cleanness. You could only approach God in worship if you ate certain foods and not others, wore certain forms of dress, refrained from touching a variety of objects, and so on. This vividly conveyed, over and over, that human beings are spiritually unclean and can’t go into God’s presence without purification.

But even in the Old Testament, many writers hinted that the sacrifices and the temple worship regulations pointed forward to something beyond them (cf. 1 Sam. 15:21-22; Ps. 50:12-15; 51:17; Hos. 6:6). When Christ appeared he declared all foods clean (Mark 7:19), and he ignored the Old Testament cleanliness laws in other ways, touching lepers and dead bodies.

The reason is clear. When he died on the cross the veil in the temple tore, showing that he had done away with the need for the entire sacrificial system with all its cleanliness laws. Jesus is the ultimate sacrifice for sin, and now Jesus makes us clean.

The entire book of Hebrews explains that the Old Testament ceremonial laws were not so much abolished as fulfilled by Christ. Whenever we pray “in Jesus name” we “have confidence to enter the Most Holy Place by the blood of Jesus” (Heb. 10:19). It would, therefore, be deeply inconsistent with the teaching of the Bible as a whole if we continued to follow the ceremonial laws.

Law Still Binding

The New Testament gives us further guidance about how to read the Old Testament. Paul makes it clear in places like Romans 13:8ff that the apostles understood the Old Testament moral law to still be binding on us. In short, the coming of Christ changed how we worship, but not how we live. The moral law outlines God’s own character—his integrity, love, and faithfulness. And so everything the Old Testament says about loving our neighbor, caring for the poor, generosity with our possessions, social relationships, and commitment to our family is still in force. The New Testament continues to forbid killing or committing adultery, and all the sex ethic of the Old Testament is re-stated throughout the New Testament (Matt. 5:27-30; 1 Cor. 6:9-20; 1 Tim. 1:8-11). If the New Testament has reaffirmed a commandment, then it is still in force for us today.

The New Testament explains another change between the testaments. Sins continue to be sins—but the penalties change. In the Old Testament sins like adultery or incest were punishable with civil sanctions like execution. This is because at that time God’s people constituted a nation-state, and so all sins had civil penalties.

But in the New Testament the people of God are an assembly of churches all over the world, living under many different governments. The church is not a civil government, and so sins are dealt with by exhortation and, at worst, exclusion from membership. This is how Paul deals with a case of incest in the Corinthian church (1 Cor. 5:1ff. and 2 Cor. 2:7-11). Why this change? Under Christ, the gospel is not confined to a single nation—it has been released to go into all cultures and peoples.

Once you grant the main premise of the Bible—about the surpassing significance of Christ and his salvation—then all the various parts of the Bible make sense. Because of Christ, the ceremonial law is repealed. Because of Christ, the church is no longer a nation-state imposing civil penalties. It all falls into place. However, if you reject the idea of Christ as Son of God and Savior, then, of course, the Bible is at best a mishmash containing some inspiration and wisdom, but most of it would have to be rejected as foolish or erroneous.

So where does this leave us? There are only two possibilities. If Christ is God, then this way of reading the Bible makes sense. The other possibility is that you reject Christianity’s basic thesis—you don’t believe Jesus is the resurrected Son of God—and then the Bible is no sure guide for you about much of anything. But you can’t say in fairness that Christians are being inconsistent with their beliefs to follow the moral statements in the Old Testament while not practicing the other ones.

One way to respond to the charge of inconsistency may be to ask a counter-question: “Are you asking me to deny the very heart of my Christian beliefs?” If you are asked, “Why do you say that?” you could respond, “If I believe Jesus is the resurrected Son of God, I can’t follow all the ‘clean laws’ of diet and practice, and I can’t offer animal sacrifices. All that would be to deny the power of Christ’s death on the cross. And so those who really believe in Christ must follow some Old Testament texts and not others.”

Sabbath Rest

Here are a few words of wisdom by Tim Keller on our need for rest.

Keller writes:

In the Bible, Sabbath rest means to cease regularly from and to enjoy the results of your work. It provides balance: ‘Six days you shall labor and do all your work, but the seventh day is a Sabbath to the Lord your God’ (Exodus 20:9–10). Although Sabbath rest receives a much smaller amount of time than work, it is a necessary counterbalance so that the rest of your work can be good and beneficial.

God liberated his people when they were slaves in Egypt, and in Deuteronomy 5:12–15, God ties the Sabbath to freedom from slavery. Anyone who overworks is really a slave. Anyone who cannot rest from work is a slave – to a need for success, to a materialistic culture, to exploitative employers, to parental expectations, or to all of the above. These slave masters will abuse you if you are not disciplined in the practice of Sabbath rest. Sabbath is a declaration of freedom.

Thus Sabbath is about more than external rest of the body; it is about inner rest of the soul. We need rest from the anxiety and strain of our overwork, which is really an attempt to justify ourselves—to gain the money or the status or the reputation we think we have to have. Avoiding overwork requires deep rest in Christ’s finished work for your salvation (Hebrews 4:1–10). Only then will you be able to ‘walk away’ regularly from your vocational work and rest.

Sabbath is the key to getting this balance, and Jesus identifies himself as the Lord of the Sabbath (Mark 2:27– 28) – the Lord of Rest! Jesus urges us, ‘Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls’ (Matthew 11:28–29). One of the great blessings of the gospel is that he gives you rest that no one else will.

“The Reason for Joy”

Here is a great quote from Timothy Keller on “The Reason for Joy.”

If you’re a Christian, you know that Christianity is supposed to be about joy. You probably also know that you’re supposed to experience joy in spite of circumstances. The Bible clearly teaches that joy is available that should make us happy no matter the circumstances. There’s a joy that the deepest trouble can’t put out and, if properly nourished and nurtured, can even overwhelm the greatest grief.

When Jesus prays to the Father in John 17:13, he prays for us – his followers. He says, I pray that ‘they may have the full measure of my joy within them.’ One chapter before, he says to his disciples, ‘You will rejoice, and no one will take away your joy’ (16:22). That’s pretty amazing! He’s talking to the twelve disciples, men who are going to be persecuted. They’re going to be robbed of everything they own, tortured, and put to death. Yet Jesus promises to give them a joy that will withstand all that. Nothing – not disease or persecution or alienation or loneliness or torture or even death – will be able to take it away.

I often wrestle with that concept. I have to ask myself, ‘Why do things affect me so much? Why is my joy not relentless?’ Sometimes I wonder, ‘Do we have that kind of impervious joy?’ I’m afraid not. I don’t think we understand the nature of this joy.

Romans 8 is all about living in a suffering world marked by brokenness. Paul talks about trouble and persecution and nakedness and poverty and how Christians are supposed to live in a world like that. In 8:28-30 he offers three principles for finding joy in suffering. Paul tells us that if we follow Christ, our bad things turn out for our good, our good things cannot be lost, and our best things are yet to come. Those are the reasons for our joy.
