THE CROSS OF CONSTANTINE

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. {GC 49.2}
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. {GC 50.1}
