Apostasy

Apostasy is the deliberate abandonment or repudiation of a faith one has previously professed — not a single sin or a season of doubt, but a settled turning away from the God or the gospel one had claimed. The English word comes from the Greek apostasia, "a standing away from," a defection or revolt, and the concept appears in Scripture under several different expressions: forsaking, falling away, shrinking back, denying.

What the text says is that apostasy is possible for those who have been close to God. David warns Solomon that if he seeks God he will be found, "but if you forsake him, he will cast you off forever" (1 Chronicles 28:9). Paul speaks of the Spirit expressly saying that "in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons" (1 Timothy 4:1), and describes people who hold "a form of godliness but having denied its power" (2 Timothy 3:5). Second Peter speaks of false teachers who "deny even the Master who bought them" (2 Peter 2:1), and of those who, having escaped the world's defilement through the knowledge of Christ, are again entangled and overcome, so that "the last state has become worse for them than the first" (2 Peter 2:20), like the dog returning to its vomit (2 Peter 2:22). Hebrews describes the case most sharply: those once enlightened, who tasted the heavenly gift and were made partakers of the Holy Spirit, who then fall away, crucifying the Son of God again — and it speaks of the one who has "trodden under foot the Son of God" and "counted the blood of the covenant with which he was sanctified an unholy thing" (Hebrews 10:29).

The tension is inside the text, not only in later theology. Alongside these warnings stand statements of confidence and perseverance: "we are not of those who shrink back to destruction, but of those who have faith to the saving of the soul" (Hebrews 10:39), and Paul's own discipline of his body "lest by any means, after I have preached to others, I myself should be disqualified" (1 Corinthians 9:27) — a word meaning failing the test, being found unapproved. Scripture also names the end of the matter: judgment on those who "didn't believe the truth, but had pleasure in unrighteousness" (2 Thessalonians 2:12).

Christian traditions read this body of teaching differently, and the difference is confessional rather than merely exegetical. Reformed teaching holds that the warnings are real means by which God preserves the elect, so that persistent apostasy reveals that a profession was never genuine, and true believers persevere. Arminian and Wesleyan teaching holds that genuinely regenerate believers can fall away and be finally lost, and reads Hebrews 6 and 10 as warnings addressed to real believers who may really forfeit salvation. Roman Catholic and Orthodox theology commonly distinguish apostasy — total repudiation of the Christian faith — from heresy, the denial of a particular doctrine, and from schism, a breach of communion, and treat apostasy as severing one from the Church while holding out repentance and reconciliation as the way back; in that tradition Hebrews 6 is often read as describing a settled and final impenitence rather than any single act of denial.
