The apostle Paul, in his second letter to the Thessalonians, foretold the great apostasy which would result in the establishment of the papal power. He declared that the day of Christ should not come, “except there come a falling away first, and that man of sin be revealed, the son of perdition; who opposeth and exalteth himself above all that is called God, or that is worshiped; so that he as God sitteth in the temple of God, showing himself that he is God.” And furthermore, the apostle warns his brethren that “the mystery of iniquity doth already work.”2 Thessalonians 2:3, 4, 7. Even at that early date he saw, creeping into the church, errors that would prepare the way for the development of the papacy.

Little by little, at first in stealth and silence, and then more openly as it increased in strength and gained control of the minds of men, “the mystery of iniquity” carried forward its deceptive and blasphemous work. Almost imperceptibly the customs of heathenism found their way into the Christian church. The spirit of compromise and conformity was restrained for a time by the fierce persecutions which the church endured under paganism. But as persecution ceased, and Christianity entered the courts and palaces of kings, she laid aside the humble simplicity of Christ and His apostles for the pomp and pride of pagan priests and rulers; and in place of the requirements of God, she substituted human theories and traditions. The nominal conversion of Constantine,in the early part of the fourth century, caused great rejoicing; and the world, cloaked with a form of righteousness, walked into the church. Now the work of corruption rapidly progressed. Paganism, while appearing to be vanquished, became the conqueror. Her spirit controlled the church. Her doctrines, ceremonies, and superstitions were incorporated into the faith and worship of the professed followers of Christ.
