Is Christian Doctrine and Conduct Rooted in the OT?

Is Christian Doctrine and Conduct Rooted in the OT?

There are many today teaching that the New Testament Church conduct and doctrine is not rooted in the Tenach, i.e. the Old Testament scriptures.  Is this is true?  Can we just simply disconnect from the “Old Testament” and cast it away?  Let’s test this by searching through the teachings of Jesus and the Apostles and see for ourselves if this hypotheses stands.

The Two Greatest Commandments

Jesus was asked about the greatest commandment and he responds by quoting from the Torah.

First and Greatest Commandment

Jesus quotes Deut 6 to show that the commands given to Moses are still applicable to his disciples

  • Mark 12:29-30 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
  • Deut 6:1 Now these are the commandments, the statutes, and the judgments, which the LORD your God commanded to teach you, that ye might do them in the land whither ye go to possess it:
  • Deut 6:4-5 Hear, O Israel: The LORD our God is one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.

Second Greatest Commandment

Jesus quotes from Lev for the second greatest commandment.  As you can see from the prophet Zech, God hates it when you imagine evil in your heart against your neighbor.  Jesus taught the exact same thing.

  • Matthew 22:39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
  • Lev 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the Lord.
  • Lev 19:34 But the stranger that dwelleth with you shall be unto you as one born among you, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the Lord your God.
  • Zech 8:17 And let none of you imagine evil in your hearts against his neighbour; and love no false oath: for all these are things that I hate, saith the Lord.

Abstain from Idols

The second of the ten commandments given to Moses is to abstain from idols and the apostles confirm this commandment.

  • 1 John 5:21 Little children, keep yourselves from idols. Amen.
  • 1 Cor 10:14 Therefore, my beloved, flee from idolatry.
  • 1 Thess 1:9 For they themselves report what kind of welcome you gave us, and how you turned away from idols to serve the living and true God;
  • Exodus 20:4-5 Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;

Obey Your Parents

Paul instructed the children to obey their parents and directly correlates it to the fifth commandment.  Paul additionally states that this is the first commandment with promise communicating to the reader that:  1. The commandments are for believers in Jesus Christ 2. There are other commandments with promises

  • Eph 6:1 Children, obey your parents in the Lord: for this is right.
  • Eph 6:2 Honour thy father and mother; (which is the first commandment with promise;)
  • Exodus 20:12 Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.

Caring for the Laborer

Paul appeals to the law of Moses, also simply referred to as the scriptures to teach about taking care of the laborer.  In this example, Paul directly quotes the law of Moses to instruct the NT church.  This command is not even part of the 10 commandments, yet Paul refers back to it as though this command is still applicable for conduct in the house of God.

  • 1 Tim 5:18 For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward.
  • 1 Cor 9:9 For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?
  • Deut 25:4 Thou shalt not muzzle the ox when he treadeth out the corn.

Woman Not Having Authority Over the Man

In this example, both Peter and Paul use Genesis to establish their doctrine and conduct for the Church.

  • 1 Tim 2:12-13 But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence. For Adam was first formed, then Eve. And Adam was not deceived, but the woman being deceived was in the transgression.
  • 1 Peter 3:5-6 For after this manner in the old time the holy women also, who trusted in God, adorned themselves, being in subjection unto their own husbands:  Even as Sara obeyed Abraham, calling him lord: whose daughters ye are, as long as ye do well, and are not afraid with any amazement.

Keeping Passover and Feast of unleavened bread

In a corrective letter to the Corinthians, Paul instructs the church to keep Passover and feast of unleavened bread.

  • 1 Cor 5:7-8 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.

Put away evil persons from among you

Here Paul instructs the Corinthians to put away evil from among them.  This commandment came directly from the Torah, the law of God.  Notice that Paul did not instruct the Church to perform capital punishment as in putting someone to death.  He did however instruct by example, to turn people over to Satan for the destruction of their flesh.

  • 1 Cor 5:13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.
  • Deut 19:19b … so shalt thou put the evil away from among you.
  • Deut 17:7b … So thou shalt put the evil away from among you.


In closing, we can see that the New Testament doctrines and conduct is clearly rooted in the Old Testament scriptures.

The Best Part of President Trumps State of the Union Address


Let us not forget that:

I wish I could see this speech as something other than a charade to string his supporters along. Trump’s actions don’t match his rhetoric. He signed for government funding of Planned Parenthood – half a billion dollars. He did nothing to stop abortion in America in his first two years while Republicans controlled Congress. Now that the Democrats control the House again, he gives a lofty pro-life speech but knows nothing will happen. (Mike Fisch)
