Apostacy means a departure from the faith that was deliver to us by the apostles.
The faith that was delivered to us by the apostles can be found in the New Testament, especially written by the apostle Paul. Paul is the only apostle that really understood what New Covenant Christianity was. There is no such thing as Old Covenant Christianity. Old Covenant law and religion has been abolished, Ephesians 2:15. Jesus nailed the Old Covenant to his cross, Colossians 2:14. To be under the law of the Old Covenant is to be under the curse, "For as many as are of the works of the law are under the curse: for it is written, cursed is everyone that does not continue to do everything that is written in the book of the law, to do them" Galatians 3:10.
The book of the law contains over 2,000 laws and rules. It is not possible to observe all of the laws and rules that are in the book of the law. Sin is the transgression of the law, 1 John 3:4. This is why Paul wrote, "There is none righteous, no, not one" Romans 3:10. All have failed to keep God's law and are sinners.
God sent Jesus into the world to save fallen man from his sins, "God so loved the world that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life" John 3:16. To believe in Jesus is to believe the New Covenant. Jesus is the end and the fulfillment of the Old Covenant, "Christ is the end of the law for righteousness to everyone that believes" Romans 10:4. Righteousness is no longer by laws, works of religion. Righteousness is only available by faith and not by works, laws and religion, "But to him that does no works, but believes on him that justifies the ungodly, his faith is counted for righteousness" Romans 4:5.
Many believe that they can be saved by the works of the law. They have departed from the faith and are in a state of apostasy, They are not able to live by faith alone. Paul who was a New Covenant Christian wrote, "For therein is the righteousness of God revealed from faith to faith: as it is written, THE JUST SHALL LIVE BY FAITH. For the wrath of God is revealed from heaven against all unrighteousness of men, who hold the truth in unrighteousness" Romans 1:17-18. To live by laws, rules and religion is to live in a state of apostacy and to be under God's wrath.
