Do Christians Pick And Choose Which Rules They Want To Follow?

Christians, it seems, are concerned about right and wrong. What are they supposed to do? How should they live? What should they do to please God? One of the most common criticisms I’ve heard from non-believers is that Christians are overbearing with their rules and seem to want to impose their rules on everyone else. Even worse, Christians themselves pick and choose which rules they want to follow. Non-believers often point out some of the “Old Testament” rules that contemporary Christians refuse to follow. Why are Christians so judgmental when they don’t even follow their own rules (such as the Old Testament regulations related to dietary restrictions or ceremonial cleaning)?

Do Christians just pick and choose the rules they want to follow?

It is important for us to consider the purpose of the “Old Testament Law,” and to distinguish between the Ten Commandments and the “Levitical Laws” (such as the dietary prohibitions). The Ten Commandments were given to Moses after he led the Israelites out of Egypt, and Moses also delivered numerous other laws (usually cited in the book of Leviticus) the Israelites were expected to follow. However, moral laws did not originate with Moses.

An enormous period of time passed between creation and the life of Moses. During this extended period before the law was given, right and wrong still existed. One of the Ten Commandments is “Thou shall not murder,” but it wasn’t this commandment which made murder wrong. Murder was always wrong, even before the Ten Commandments were given. The Old Testament records many instances of murder prior to the time of Moses and always describes it as wrong. The moral law, including the moral implications of murder, predated the Law of Moses, and people were expected to face the consequences of their own immoral behavior. The Levitical Law also included many laws which did not exist prior to the time of Moses. Specific requirements such as what kinds of food you could eat were given in these laws and God expected the Israelites to follow them.

There is something of a parallel in American history. I was born and raised in California. In school we learned the history of our state, and so I know, for example, that California did not formally become a state until 1850. One of the first things California did was establish the criminal laws and set up law enforcement (local county sheriffs) to enforce those laws. One of these laws made it illegal to commit murder in California. This allowed the Sheriffs to pursue murderers and gave them legal authority to stop them. However, in the time before the law against murder was formally written into law, it was still wrong to murder. The law of the new state of California simply reflected a pre-existing moral law. If tomorrow California recalled Penal Code Section 187, which prohibits murder, it would impact my legal authority to investigate murderers, but it wouldn’t make murder morally right.

California law also includes some rules which are more practical than moral in nature. For example, the speed limit on my street is 25 miles per hour. Before the speed limit was written into law, it wouldn’t have been in and of itself immoral to drive 26 miles per hour, and it wouldn’t have been wrong for the law to be re-written as 20 miles per hour. But now that it is set at 25, I’m expected to follow it. The speed limit laws may not be based on pre-existing moral laws, but they do help our society practically achieve one of our goals, namely safety, and the speed limit useful for that purpose.

The Ten Commandments and the Levitical laws were given to the Israelites after Moses led them out of Egypt, where they previously lived under the rule of Egyptian laws. Now, Israel was going to become its own nation and Moses provided them with direction. Some aspects of the law, such as the Ten Commandments, put into writing pre-existing moral obligations, just like the California laws related to murder. Other portions of the Law contain practical rules that the Israelites were expected to follow (such as the dietary restrictions). One of the purposes of these restrictions was to symbolize that the Israelites were set apart by God and were different from the surrounding cultures. Now that it was written into law, the Israelites were expected to follow it just as you and I would be expected to follow speed limit laws.

But why don’t Christians today follow these secondary laws described by Moses?

The New Testament specifically tells Christians there is a new covenant between God and his people.  Jesus himself said he came to “fulfill the law” (Matthew 5:17). The Apostle Peter was given a vision by God in which God explicitly told Peter that dietary laws were no longer obligatory (Acts 10). Throughout the new Testament the Apostle Paul taught that the Christians were not beholden to many of Levitical laws, such as the requirement that one be circumcised.

Christians today do not “pick and choose” which portions of the Bible they follow. Instead, they recognize that the Levitical laws were written for a specific people, at a specific time, in a specific location. These practical obligations don’t apply to us, any more than the dietary law applied to Peter. The Ten Commandments represent a different set of moral ordinances, however. They spring from the very nature of God who hasn’t changed. The moral law today is the same as it was before it was given to Moses because God is the same today as He has been from all eternity. Christians today do not “pick and choose” which portions of the Bible they follow. Instead, they recognize that the Levitical laws were written for a specific people, at a specific time, in a specific location. Share on X

That unchanging aspect of the moral Law condemns us because it highlights our imperfection and our need for a Savior. But it also points us to the cross and the saving work of the one perfectly obedient man, Jesus, who stands in our place.

    But why God gives different laws to different people? If God is the unchanging same why do Americans and Indians needs to receive different laws? Was God change with the change of culture and time? If Paul says the Levitical laws were no more mandatory why? Please illustrate me with more insights.

      I was hoping to hear the author’s thinking about observance of the fourth commandment, because, as written, this commandment doesn’t seem to be followed by Christianity much today. On the surface, this moral commandment seems to be treated as ‘pick and choose.’

      Fleshing this out, the key point that Christianity is under the law of the new covenant.
      In Matt 22, a Pharisee and expert in the law addresses this very issue to Jesus:

      36.Teacher, which is the greatest commandment in the Law?”

      37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’[c] 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’[d] 40 All the Law and the Prophets hang on these two commandments.”

      Paul points out that love overcomes all laws. The purpose of the law is predominately there to enable us to see we are unable to live by the law, and we need salvation.

        17 “Don’t think that I have come to destroy the law of Moses or the teaching of the prophets. I have not come to destroy their teachings but to do what they said.18 I tell you the truth. Nothing will disappear from the law until heaven and earth are gone. The law will not lose even the smallest letter or the smallest part of a letter until all has happened.19 Whoever refuses to obey any command and teaches other people not to obey that command will be the least important in the kingdom of heaven. But whoever obeys the law and teaches other people to obey the law will be great in the kingdom of heaven.20 I tell you that you must do better than the teachers of the law and the Pharisees. If you are not better than they are, you will not enter the kingdom of heaven. – Matthew 5:17-20
