•the rejection of Christ by someone who formerly was a Christian
•defection, departure, revolt or rebellion
•the antonym of conversion
•the theological category that describes those who have voluntarily and consciously abandoned their Faith in the God of the covenant, who manifests himself most completely in Jesus
The New Testament describes at least three apostasy dangers:
•Temptations: Christians were tempted to engage in various vices that were a part of their lives before they became Christians, such as idolatry and sexual immorality.
•Deceptions: Christians encountered various heresies and false teachings spread by false teachers and prophets that threatened to seduce them away from their pure devotion to Christ.
•Persecutions: Christians were persecuted by the governing powers of the day for their allegiance to Christ. Many Christians were threatened with certain death if they would not deny Christ.
God rejects apostasy and false teaching.
“Let no one in any way deceive you, for it [Jesus’ return] will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction.” (2 Thessalonians 2:3)
An apostate believed and then rejected the truth. Apostasy is a rebellion against God, because it is a rebellion against the truth, and is associated with The Antichrist. His arrival cannot occur until sufficient apostasy exists in the world. The Bible says the apostasy will come first, and then the Antichrist will be revealed.
Christians must cling to the truth, because apostates do not enter into Heaven. A Christian becomes an apostate when he joins a non-Christian religion, like Judaism, Buddhism, Islam, or falls into unbelief, atheism, materialism, agnosticism, rationalism, indifferentism, secularism or “free-thought”.
