CIC 675 Before Christ’s second coming the Church must pass through a final trial that will shake the faith of many believers.1 The persecution that accompanies her pilgrimage on earth2 will unveil the “mystery of iniquity” in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh.3
