In Galatians 1:9As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.
See All..., it says that if anyone preaches a gospel that is different than the one you accepted, may he be condemned to hell. What does this mean?

Let's look at the verse in question.

Galatians 1:9As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.
See All... “As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.”

First off I would like to clarify what “that ye have received” means. Please remember that the epistles were literal letters written to literal churches, people etc. Paul or someone he taught delivered the gospel to these churches so he could be confident to say that the gospel they had received was the true gospel. This does not apply directly to everyone today because some have received a gospel, but it is not the same gospel that Paul preached.

Now let us look at the phrase “let him be accursed.” Some of the modern versions will translate this phrase as “condemned to hell”. The problem with this is instead of translating it for you, they have interpreted it for you and have done so incorrectly. The best way to interpret any scripture is by letting the Bible interpret itself. Let’s look at the uses of the different forms of the word “accursed”.

• The Serpent (Genesis 3:14And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
  See All...)
• The Ground (Genesis 3:17And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
  See All...)
• Cain (Genesis 4:11And now art thou cursed from the earth, which hath opened her mouth to receive thy brother's blood from thy hand;
  See All...)
• Canaan (Genesis 9:25And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren.
  See All...)
• The Anger of Simeon and Levi (Genesis 49:7Cursed be their anger, for it was fierce; and their wrath, for it was cruel: I will divide them in Jacob, and scatter them in Israel.
  See All...)
• The Man that rebuilds Jericho (Joshua 6:26And Joshua adjured them at that time, saying, Cursed be the man before the LORD, that riseth up and buildeth this city Jericho: he shall lay the foundation thereof in his firstborn, and in his youngest son shall he set up the gates of it.
  See All...)
• Jezebel (2 Kings 9:34And when he was come in, he did eat and drink, and said, Go, see now this cursed woman, and bury her: for she is a king's daughter.
  See All...)

• He that is hanged on a tree (Deuteronomy 21:23His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
  See All...)
• The City of Jericho (Joshua 6:17And the city shall be accursed, even it, and all that are therein, to the LORD: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.
  See All...)
• The Things Consecrated unto the Lord (Joshua 6:18And ye, in any wise keep yourselves from the accursed thing, lest ye make yourselves accursed, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it.
  See All...)
• The Children of Israel (Joshua 7:12Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because they were accursed: neither will I be with you any more, except ye destroy the accursed from among you.
  See All...)
• The Apostle Paul wished of Himself (Romans 9:3For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh:
  See All...)
• No man by the Spirit calls Jesus accursed (1 Corinthians 12:3Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost.
  See All...)

Now that we have seen these occurrences in scripture, let us plug in a couple of definitions for “let him be accursed”. If it means “condemned to hell,” then we must say that the ground in Genesis 3:17And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
See All..., the anger of Simeon and Levi in Genesis 49:7Cursed be their anger, for it was fierce; and their wrath, for it was cruel: I will divide them in Jacob, and scatter them in Israel.
See All..., anyone hung on tree (Deuteronomy 21:23His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
See All..., the city of Jericho (Joshua 6:17And the city shall be accursed, even it, and all that are therein, to the LORD: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.
See All...), and the children of Israel (Joshua 7:12Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because they were accursed: neither will I be with you any more, except ye destroy the accursed from among you.
See All...) are all condemned to hell. This does not fit with the rest of scripture.

Another problem with the idea of those preaching another gospel being condemned to hell is that our gospel is very plain that salvation is only by grace through faith and that there are no works involved (Ephesians 2:8-9 [8] For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: [9] Not of works, lest any man should boast.
See All...). There are many who preach that you can only be saved by grace but you must live it in order to keep your salvation. Let’s apply the verse to this person. They got saved “by grace through faith”, yet someone taught them that they could lose their salvation and so they began preaching this to others. This is not the true gospel so according to the interpretation given by most this person would now be condemned to hell for preaching a false gospel but if they can now lose it then they were preaching the right gospel in the first place. This just goes to show that this interpretation does not work.

Deuteronomy 21:23His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
See All... will give us a key for interpreting the usage and purpose of someone being accursed.

Deuteronomy 21:23His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
See All... His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.

The person that was hung on the tree was accursed so that the land would not be defiled. What does this mean? It means that the children of Israel were to put this man out of the congregation (death in the Old Testament) so as to not defile the land for those who were innocent. This applies very well in context with what Paul is saying in Galatians. If you have someone in the church that is preaching a false gospel, then it is very likely that there will be some young believers who will be led astray. So what were they to do? They were to “let him be accursed” or remove him from the congregation so that the rest were not defiled by his false teaching. In the New Testament we are not to kill those who do not preach sound doctrine, but we are to remove them from our church before they corrupt others.

God desires purity in the church and that includes purity in doctrine. The local assemblies are not to be defiled by someone preaching another gospel even if it is a twist on the truth.
