What is An Apostate Christian?

apostasy pic2Apostasy is a grievous sin. It means “to fall away” from the faith. In the same way that Lucifer and one third of the angels fell away from God, Christians can fall away from God. I won’t argue whether they were ever with God or not, but at some point they made a public declaration of their rebellion.

For Lucifer, the moment of rebellion came when he proudly declared he wanted to be

like the Most High” (Isa. 14:14b, KJV). Adam and Eve fell in the same way. The serpent told Eve she wouldn’t die, but would have her eyes opened and would “be as gods” (Gen. 3:5, KJV), “knowing good and evil” (Gen. 3: 4, KJV).


Apostate Christians believe the same lies as Eve and the fallen angels. They believe in extra-biblical (something added to the Word of God) teachings or revelations that claim to make them wise–even if it conflicts with the Word of God.

The beginning of all evil can be found in this inclination to add to the Word of God. The Old Testament prophets, and even Jesus, called this a form of spiritual adultery. Is it any coincidence that Ezekiel, Jeremiah, Hosea, and all the other Old Testament prophets framed their arguments against apostate Israel in terms of a marriage relationship?

Jeremiah revealed the heart of God when he said Israel “played the harlot with many lovers” (Jer. 3:1, KJV) when she added Baal worship to the worship of Yahweh. Because the Israelites of Jeremiah’s time never stopped worshiping God, and just added Baal (the god of prosperity and fertility) to their worship, they never even considered that they had fallen from God.

Hosea was even commanded to marry an unfaithful woman as an allegorical picture of Israel’s adultery. God lamented the situation, asking how long his people would be incapable of purity (Hosea 8:5). To Him, Israel was like an unfaithful wife who kept other lovers on the side.

Jesus carried on this line of thought when he pointed to the Pharisees and Sadducees and called them “a wicked and adulterous generation” (Matt. 16:4). Why were they evil? Because they needed the addition of a “sign” (the Word wasn’t enough) to prove Jesus was the Messiah, and they had added their own traditions to the Word of God, “teaching for doctrines the commandments of men” (Mark 7:7).

In the Old Testament, the Hebrew word na’aph means both “apostasy” and “adultery.” (1)  The Greek word for “adultery” is moicheuo. (2) Its root word is moichos, (3) which, like the Old Testament word for adultery (na’aph), also refers to an apostate. In fact, the Greek word for “falling away” is apostasia. It means “defection from truth, apostasy, falling away, forsake.”(4)

Spiritual adultery (adding something to the worship of God, or adding to his Word) is the same thing as apostasy! It’s also the same thing as falling away from God. When Satan added his lies to the Word, and Eve believed them and ate of the forbidden tree, or when one third of the angels believed they could worship God AND Satan, they fell away from God.

When the Christian church adds to the Word, or worships something alongside of the Word, they are fallen away from God. As I hope I’ve documented on this website, spiritual adultery, or apostasy, has happened over and over in Christian history, and when it occurs, it’s always accompanied by war, torture, slavery, abuse, genocide, tyranny, and all other forms of human suffering.

While progressives and atheists point to fundamentalist Christians as purveyors of evil, nothing could be further from the truth. History reveals that it was apostates who betrayed God, and consequently, betrayed humanity.

When Adam and Eve ate of the forbidden fruit, the whole world fell from a state of perfect provision–and human suffering began. When Israel began worshiping Baal or Molech alongside of Yahweh, they no longer treated each other with kindness and love (read Isaiah 1!).

And when the church began to blend Greek philosophy and Roman ritualism with the Word, darkness began to descend upon all of western civilization. It remained in that state of darkness for a millennium–until the call went out during the Reformation to return to the Word alone (sola scriptura) as our source of truth.

There have always been two entities in the world claiming to be the CHURCH, but only one of them is the true church. The other is an apostate. She is a harlot with other lovers on the side. Using the name of “Jesus,” she goes around seducing people away from the truth of the Word, convincing them that they will be wiser for it. No need to get rid of God–just add the current wisdom of the world to the teachings of Christ and create a jumbled up blend that is no longer the truth. And by the way, the destruction that follows can be blamed on God!

For God’s sake, can’t we keep the Word of God pure?

• It was the false church who burned people at the stake by blending in Greek philosophy, Roman ritualism, and false teaching with the doctrines of Christ.

• It was the false church who squelched science by blending Aristotelian natural philosophy into the doctrines of Christ.

• It was the false church who supported slavery by blending scientific racism (polygenism) in with the doctrines of Christ.

• It was the false church that supported abusive colonialism by blending Darwinism into the doctrines of Christ.

• It was the false church who supported Nazism by blending in the latest philosophy (Hegelianism) and science (Darwinism) in with the teachings of Christ.

The burning, torture, and tyranny of the Inquisition, slavery, the Holocaust, ignorance, and abuse of the helpless has never been caused by a faithful Christian who loves the Bible and keep its doctrines pure, but it has always been caused by an apostate Christian who tosses aside the Word of God for another source of wisdom.

We can see this same challenge in our own generation. How many Christians have gone astray by adding Darwinism, psychology, quantum physics, prophetic revelations, political ideologies, business principles, mammon (through the prosperity gospel), angelic visitations (such as those that began Islam or Mormonism), ecumenism, contemplative spirituality, dreams, visions, or even fictional narratives (such as the book The Shack)?

Whether or not a person is faithful to the scriptures is a sure way to discern whether a person has become apostate. If a Christian places other sources of knowledge or wisdom above, or beside, the sure teachings of the scriptures, they may be going astray in much the same way as an unfaithful spouse–and someone will suffer for their unfaithfulness to God.  Satan and Adam and Eve are examples of the consequences that come from falling away.

Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God. Moreover it is required in stewards, that a man be found faithful.” (1 Cor. 4:1-2, KJV)

  1. They believe in extra-biblical (something added to the Word of God) teachings or revelations that claim to make them wise–even if it conflicts with the Word of God Not really. I/we just don’t believe the story. I’ve not added nor subtracted to claim any special wisdom at all. The story is so full of holes any rational person that actually read it would see it’s fiction. Made up. That’s all. 2000 years of non results. No blind see, no lame are healed. No signs follow any of you. With the kind of domination Christianity has had, the world should be pure bliss by now. You have a monopoly and have failed to produce results. That’s it. Pretty simple.


    1. If it’s in the Bible it’s the truth, but some people who believed in God have added their philosophical, scientific, or other types of views to Christianity and created a monstrous mix. For example, science was stunted when the medieval Catholic church blended Aristotle’s “natural philosophy” in with church teachings. In order for science to thrive scientists had to break the stranglehold that Greek philosophy had on the church. Galileo wasn’t fighting against the teachings in the Bible; he was fighting against Aristotelian views set up as truth in the church. If church doctrine would have remained pure, this conflict would not have happened. Aristotle believed that the earth was at the center of the solar system. The Bible doesn’t teach that. Aristotle believed that the earth was made up of four elements (earth, water, air, and fire). The Bible doesn’t teach that. Aristotle believed in spontaneous generation. The Bible certainly doesn’t teach that. Francis Bacon, the founder of the scientific method, wrote “The New Organon” to counter Aristotle’s “Organon.” Aristotle’s teachings were fables while the Bible teachings are the truth. Perhaps you could read more about this in my post, “God and the Scientific Revolution.”

      1. So the people that believed in god, added to the Bible on their own, took out what they wanted, included traditional stories that never happened, somehow make the Bible true? You don’t really believe that do you? Noah, the ark, the exodus with Moses, not even the Jews believe those any more. Geopolitical fiction, is what they’re calling it. This isn’t even new. What’s up?


      2. I believe the Bible is true because it’s message is miraculous, it has always been on the right side of history, and because there is evidence everywhere that points to its truthfulness. The fact that people weren’t faithful to its message doesn’t make me reject the Bible.
