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, shewing 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. SR 326.1
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, arrayed in robes 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. SR 326.2
This compromise between paganism and Christianity resulted in the development of the man of sin foretold in prophecy as opposing and exalting himself above God. That gigantic system of false religion is a masterpiece of Satan's power—a monument of his efforts to seat himself upon the throne to rule the earth according to his will. SR 327.1
To secure worldly gains and honors, the church was led to seek the favor and support of the great men of earth, and having thus rejected Christ, she was induced to yield allegiance to the representative of Satan—the Bishop of Rome. SR 327.2
It is one of the leading doctrines of Romanism that the pope is the visible head of the universal church of Christ, invested with supreme authority over bishops and pastors in all parts of the world. More than this, the pope has arrogated the very titles of Deity. SR 327.3
Satan well knew that the Holy Scriptures would enable men to discern his deceptions and withstand his power. It was by the Word that even the Saviour of the world had resisted his attacks. At every assault Christ presented the shield of eternal truth, saying, “It is written.” To every suggestion of the adversary he opposed the wisdom and power of the Word. In order for Satan to maintain his sway over men and establish the authority of the papal usurper, he must keep them in ignorance of the Scriptures. The Bible would exalt God and place finite men in their true position; therefore its sacred truths must be concealed and suppressed. This logic was adopted by the Roman church. For hundreds of years the circulation of the Bible was prohibited. The people were forbidden to read it, or to have it in their houses, and unprincipled priests and prelates interpreted its teachings to sustain their pretensions. Thus the pope came to be almost universally acknowledged as the vicegerent of God on earth, endowed with supreme authority over church and state. SR 327.4
