Epistle to the Philippians

"For whoever does not confess that Jesus Christ has come in the flesh is antichrist; and whoever does not confess the testimony of the cross is of the devil; and whoever perverts the oracles of the Lord to his own lusts and says that there is neither a resurrection nor a judgment, he is the first-born of Satan. Therefore, forsaking the vanity of many and their false doctrines, let us return to the word which has been handed down to us from the beginning; watching unto prayer, and persevering in fasting; beseeching in our supplications the all-seeing God not to lead us into temptation, as the Lord has said: 'The spirit truly is willing, but the flesh is weak.'"
