Some Will Depart from the Faith Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons 1 Timothy 4:1, ESV
According to the words of our Lord Jesus Christ in John 15 the mark of Christian authenticity is abiding or remaining in Him. This is not simply a continual profession of faith, but a remaining faithful to Christ in our orthodox Christian faith. According to Paul, It is a two-fold action of departing from the faith and giving heed to seducingspirits, and doctrines of devils. The Apostle John called the Christian leaders who do this “antichrists.”
