The Bible warns about people like Arius (c. AD 250—336), a Christian priest from Alexandria, Egypt, who was trained at Antioch in the early fourth century. About AD 318, Arius accused Bishop Alexander of Alexandria of subscribing to Sabellianism, a false teaching that asserted that the Father, Son, and Holy Spirit were merely roles or modes assumed by God at various times. Arius was determined to emphasize the oneness of God; however, he went too far in his teaching of God’s nature. Arius denied the Trinity and introduced what appeared on the surface to be an inconsequential difference between the Father and Son.
Arius argued that Jesus was not homoousios (“of the same essence”) as the Father, but was rather homoiousios (“of similar essence”). Only one Greek letter—the iota (ι)—separated the two. Arius described his position in this manner: “The Father existed before the Son. There was a time when the Son did not exist. Therefore, the Son was created by the Father. Therefore, although the Son was the highest of all creatures, he was not of the essence of God.”
Arius was clever and did his best to get the people on his side, even going so far as to compose little songs that taught his theology, which he tried to teach to everyone who would listen. His winsome nature, asceticism, and revered position as a preacher also contributed to his cause. (gotquestions.org)
With respect to apostasy, it is critical that all Christians understand two important things: (1) how to recognize apostasy and apostate teachers, and (2) why apostate teaching is so deadly.
This book by John Owen is an excellent resource.
“Few subjects have received less attention from contemporary Christian writers than that of apostasy. The idea that professing Christians may prove not to be true Christians is, in many respects, too serious a prospect for our facile age. But, for Owen, such avoidance of the issue was itself a pressing reason for writing on it at length and in great depth of spiritual analysis. His exposition is a masterpiece of penetration and discernment.” – Banner of Truth
To fully identify and combat apostasy, Christians should understand its various forms and the traits that characterize its doctrines and teachers. As to the forms of apostasy, there are two main types:
(1) a falling away from key and true doctrines of the Bible into heretical teachings that claim to be “the real” Christian doctrine
(2) a complete renunciation of the Christian faith, which results in a full abandonment of Christ.
So, let’s look at how to recognize Apostasy….
Jude was the half brother of Jesus and a leader in the early church. In his New Testament letter, he outlines how to recognize apostasy and strongly urges those in the body of Christ to contend earnestly for the faith (Jude 1:3). The Greek word translated “contend earnestly” is a compound verb from which we get the word agonize. It is in the present infinitive form, which means that the struggle will be continuous. In other words, Jude says that there will be a constant fight against false teaching and that Christians should take it so seriously that we “agonize” over the fight in which we are engaged. Moreover, Jude makes it clear that every Christian is called to this fight, not just church leaders, so it is critical that all believers sharpen their discernment skills so that they can recognize and prevent apostasy in their midst.
After urging his readers to contend earnestly for the faith, Jude highlights the reason: “For certain persons have crept in unnoticed, those who were long beforehand marked out for this condemnation, ungodly persons who turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ” (Jude 1:4). In this one verse, Jude provides Christians with three traits of apostasy and apostate teachers:
First, Jude says that apostasy can be subtle. Apostates have “crept” into the church. In extra-biblical Greek, the term Jude uses describes the cunning craftiness of a lawyer who, through clever argumentation, infiltrates the minds of courtroom officials and corrupts their thinking. The word literally means “slip in sideways; come in stealthily; sneak in.” In other words, Jude says it is rare that apostasy begins in an overt and easily detectable manner. Instead, it looks a lot like Arius’s doctrine—only a single letter, the iota, differentiates the false teaching from the true.
Describing this aspect of apostasy and its underlying danger, A. W. Tozer wrote, “So skilled is error at imitating truth, that the two are constantly being mistaken for each another. It takes a sharp eye these days to know which brother is Cain and which is Abel.” The apostle Paul also speaks to the outwardly pleasing behavior of apostates and their teaching: “For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ. No wonder, for even Satan disguises himself as an angel of light” (2 Corinthians 11:13–14). In other words, do not look for apostates to appear bad on the outside or speak dramatic words of heresy at the outset of their teaching. Rather than denying truth outright, apostates will twist it to fit their own agenda, but, as pastor R. C. Lensky has noted, “The worst forms of wickedness consist in perversions of the truth.”
Second, Jude describes apostates as “ungodly” and as those who use God’s grace as a license to commit unrighteous acts.
Beginning with “ungodly,” Jude describes eighteen unflattering traits of apostates:
- they are ungodly (Jude 1:4),
- morally perverted (verse 4),
- denying Christ (verse 4),
- ones who defile the flesh (verse 8),
- rebellious (verse 8),
- people who revile angels (verse 8),
- who are ignorant about God (verse 8),
- those who proclaim false visions (verse 10),
- self-destructive (verse 10),
- grumblers (verse 16),
- faultfinders (verse 16),
- self-satisfying (verse 16),
- people who use arrogant words and false flattery (verse 16),
- mockers of God (verse 18),
- those who cause divisions (verse 19),
- worldly minded (verse 19),
- and finally (and not surprisingly), devoid of the Spirit/unsaved (verse 19). Nothing about their life is divinely supernatural; pointing to and glorifying God. Instead, they live in the natural; with deeds and behaviors that point to and glorify themselves.Third, Jude says apostates “deny our only Master and Lord, Jesus Christ.” They profess to know God, but by their behaviors they deny Him. How do apostates do this? Paul tells us in his letter to Titus, “To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled. They profess to know God, but by their deeds they deny Him, being detestable and disobedient and worthless for any good deed” (Titus 1:15–16). Through their unrighteous behavior, the apostates show their true selves. Unlike an apostate, a true believer is someone who has been delivered from sin to righteousness in Christ and who refuses to continue in sin (Romans 6:1–2). They hate their sin, and long to obey God in every area of their life. They live with a daily and moment-to-moment consciousness to His Word and a wholehearted surrender to know, understand, and walk in obedience to it.Ultimately, the sign of an apostate is that he eventually falls away and departs from the truth of God’s Word and His righteousness. The apostle John signifies this is a mark of a false believer: “They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us” (1 John 2:19). *gotquestions.org
Every New Testament book except Philemon contains warnings about false teaching.
Read that sentence one more time, but slowly.
Do you think then that this is critically important that we look to understand the Bible’s warnings in how to spot and determine deceitful and unauthorized teaching? The Bible gives clear distinguishing marks of those who teach truth in contrast to those who teach what “sounds like the truth?”
Why is this?
Simply because ideas have consequences. Right thinking and its fruit produce goodness, whereas wrong thinking and its accompanying action result in undesired penalties.
Satan did not come to Adam and Eve in the Garden with an external or visible weapon; instead, he came to them with an idea. And it was that idea, embraced by Adam and Eve, that condemned them and the rest of humankind, with the only remedy being the sacrificial death of God’s Son.
The great tragedy is that, knowingly or unknowingly, the apostate teacher deceives and dooms their unsuspecting followers. Speaking to His disciples about the religious leaders of His day, Jesus said, “Let them alone; they are blind guides of the blind. And if a blind man guides a blind man, both will fall into a pit” (Matthew 15:14). Alarmingly, it is not only false teachers who go to destruction, but their followers follow them there.
So, how did things end with Arius and his teaching?
In AD 325, the Council of Nicea took up the issue of Arius and his teaching, and much to his dismay, the end result was his excommunication and a statement in the Nicene Creed that affirms Christ’s divinity: “We believe in one God, the Father Almighty, maker of all things visible and invisible; and in one Lord Jesus Christ, the Son of God, the only-begotten of his Father, of the substance of the Father, God of God, Light of Light, very God of very God, begotten not made, being of one substance with the Father.”
Arius may have died centuries ago, but his spiritual children are still with us to this day in the form of cults like the Jehovah’s Witnesses and others who deny Christ’s true essence and person. Sadly, until Christ returns and every last spiritual enemy has been removed, tares such as these will be present among the wheat (Matthew 13:24–30). In fact, Scripture says apostasy will only get worse as Christ’s return approaches. “At that time [the latter days] many will fall away and will betray one another and hate one another” (Matthew 24:10). Paul told the Thessalonians that a great falling away would precede Christ’s second coming (2 Thessalonians 2:3) and that the end times would be characterized by tribulation and hollow religious charlatans…a person who pretends or claims to have more knowledge or skill than they possess; a fraud; a performer; a hypocrite – “But realize this, that in the last days difficult times will come. For men will be . . . holding to a form of godliness, although they have denied its power; avoid such men as these” (2 Timothy 3:1–2, 5).
It is critical, now more than ever, that every believer pray for discernment, combat apostasy, and contend earnestly for the faith that was once and for all delivered to the saints. (gotquestions.org)

Does saving faith always produce fruit / distinguishing marks?
Sadly, today’s gospel message rarely matches the gospel Jesus taught.
