• 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
According to B. J. Oropeza, 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 vehemently rejects apostasy and false teaching since every New Testament book, except Philemon, contains warnings about 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)
Apostasy means to fall away from the truth, and an apostate believed and then rejected the truth of God. Apostasy is a rebellion against God because it is a rebellion against truth. The above verse tells us that there will be apostasy associated with the appearance of The Antichrist. Most Christians are looking for its arrival, but very few are looking for “the apostasy” that must come first, since the arrival of the Antichrist cannot occur until sufficient apostasy has happened in the world. The Antichrist, the ultimate of liar, cannot abide in a world where the truth of God’s word is taught. The Bible says that the apostasy will come first, and then the Antichrist will be revealed.
Christians need to cling to the truth of God, and resist to liberalism, moral relativism and EVIL Secularism, because apostates do not enter Heaven. A Christian becomes an apostate when he joins a non-Christian religion, as Judaism, Buddhism, Islam, or falls into unbelief, atheism, materialism, agnosticism, rationalism, indifferentism, secularism or “free-thought”.
