Antichrist
Antichrist, literally against Christ, is someone who opposes Christ or the Christian Church. The Antichrist are considered fundamental enemies or opponents of Christ and the Christian Church as supremely evil forces.In the New Testament this name is given to various incarnations of opposition to Christ in usurpation of His authority. However, St. John has defined it to involve that form of opposition which denies the doctrine of the Incarnation, or that Christ has come in the flesh.
It is found in some Christian teachings that the Antichrists are personal opponents of Christ who would come before the end of the world to oppose Christ.
