Apostasy

Apostasy is the abandonment of genuine faith, the turning away from the living God by someone who was once part of the covenant community. It is one of the most serious categories in Scripture, treated with consistent gravity across both Testaments. The prophets describe Israel’s spiritual adultery, their turning to the gods of the nations, as apostasy from Yahweh. The New Testament warns against the same pattern of departure from the gospel.

The warning passages of Hebrews are the most direct New Testament treatment of apostasy. “It is impossible to renew again to repentance those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, and then have fallen away” (Hebrews 6:4-6). The severity of this passage has generated extensive theological debate. What is not in doubt is that the author treats the possibility of falling away as a real and serious danger that warrants urgent warning.

The New Testament’s treatment of apostasy does not undermine the doctrine of the perseverance of the saints, but it refuses to reduce it to a comfortable assurance that requires no ongoing attention. Those who truly belong to Christ will be kept by him; those who fall away reveal that they never truly belonged (1 John 2:19). The warnings are real, and so is the assurance. The articles below trace this theme through several of its key passages.
