Satan therefore laid his plans to war more successfully against the government of God, by planting his banner in the Christian church. If the followers of Christ could be deceived and led to displease God, then their strength, fortitude, and firmness would fail, and they would fall an easy prey. SR 322.1
The great adversary now endeavored to gain by artifice what he had failed to secure by force. Persecution ceased, and in its stead were substituted the dangerous allurements of temporal prosperity and worldly honor. Idolaters were led to receive a part of the Christian faith, while they rejected other essential truths. They professed to accept Jesus as the Son of God and to believe in His death and resurrection; but they had no conviction of sin and felt no need of repentance or of a change of heart. With some concessions on their part, they proposed that Christians should make concessions, that all might unite on the platform of belief in Christ. SR 322.2
Now was the church in fearful peril. Prison, torture, fire, and sword were blessings in comparison with this. Some of the Christians stood firm, declaring that they could make no compromise. Others reasoned that if they should yield or modify some features of their faith, and unite with those who had accepted a part of Christianity, it might be the means of their full conversion. That was a time of deep anguish to the faithful followers of Christ. Under a cloak of pretended Christianity, Satan was insinuating himself into the church, to corrupt their faith and turn their minds from the word of truth. SR 322.3
At last the larger portion of the Christian company lowered their standard, and a union was formed between Christianity and paganism. Although the worshipers of idols professed to be converted, and united with the church, they still clung to their idolatry, only changing the objects of their worship to images of Jesus, and even of Mary and the saints. The foul leaven of idolatry, thus introduced into the church, continued its baleful work. Unsound doctrines, superstitious rites, and idolatrous ceremonies were incorporated into her faith and worship. As the followers of Christ united with idolaters, the Christian religion became corrupted and the church lost her purity and power. There were some, however, who were not misled by these delusions. They still maintained their fidelity to the Author of truth and worshiped God alone. SR 322.4
There have ever been two classes among those who profess to be followers of Christ. While one class study the Saviour's life and earnestly seek to correct their defects and to conform to the Pattern, the other class shun the plain, practical truths which expose their errors. Even in her best estate the church was not composed wholly of the true, pure, and sincere. Our Saviour taught that those who willfully indulge in sin are not to be received into the church; yet He connected with Himself men who were faulty in character, and granted them the benefits of His teachings and example, that they might have an opportunity to see and correct their errors. SR 323.1
But there is no union between the Prince of light and the prince of darkness, and there can be no union between their followers. When Christians consented to unite with those who were but half converted from paganism, they entered upon a path which led farther and farther from the truth. Satan exulted that he had succeeded in deceiving so large a number of the followers of Christ. He then brought his power to bear more fully upon them, and inspired them to persecute those who remained true to God. None could so well understand how to oppose the true Christian faith as could those who had once been its defenders; and these apostate Christians, uniting with their half-pagan companions, directed their warfare against the most essential features of the doctrines of Christ. SR 323.2
It required a desperate struggle for those who would be faithful to stand firm against the deceptions and abominations which were disguised in sacerdotal garments and introduced into the church. The Bible was not accepted as the standard of faith. The doctrine of religious freedom was termed heresy, and its upholders were hated and proscribed. SR 324.1
