Most of the Christians at last consented to lower 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 brought 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. (GC 43.1) MC VC

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 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 their errors and correct them. Among the twelve apostles was a traitor. Judas was accepted, not because of his defects of character, but notwithstanding them. He was connected with the disciples, that, through the instruction and example of Christ, he might learn what constitutes Christian character, and thus be led to see his errors, to repent, and, by the aid of divine grace, to purify his soul “in obeying the truth.” But Judas did not walk in the light so graciously permitted to shine upon him. By indulgence in sin he invited the temptations of Satan. His evil traits of character became predominant. He yielded his mind to the control of the powers of darkness, he became angry when his faults were reproved, and thus he was led to commit the fearful crime of betraying his Master. So do all who cherish evil under a profession of godliness hate those who disturb their peace by condemning their course of sin. When a favorable opportunity is presented, they will, like Judas, betray those who for their good have sought to reprove them. (GC 43.2) MC VC

The spirit of concession to paganism opened the way for a still further disregard of Heaven’s authority. Satan, working through unconsecrated leaders of the church, tampered with the fourth commandment also, and essayed to set aside the ancient Sabbath, the day which God had blessed and sanctified (Genesis 2:2, 3), and in its stead to exalt the festival observed by the heathen as “the venerable day of the sun.” This change was not at first attempted openly. In the first centuries the true Sabbath had been kept by all Christians. They were jealous for the honor of God, and, believing that His law is immutable, they zealously guarded the sacredness of its precepts. But with great subtlety Satan worked through his agents to bring about his object. That the attention of the people might be called to the Sunday, it was made a festival in honor of the resurrection of Christ. Religious services were held upon it; yet it was regarded as a day of recreation, the Sabbath being still sacredly observed. (GC 52.1) MC VC

To prepare the way for the work which he designed to accomplish, Satan had led the Jews, before the advent of Christ, to load down the Sabbath with the most rigorous exactions, making its observance a burden. Now, taking advantage of the false light in which he had thus caused it to be regarded, he cast contempt upon it as a Jewish institution. While Christians generally continued to observe the Sunday as a joyous festival, he led them, in order to show their hatred of Judaism, to make the Sabbath a fast, a day of sadness and gloom.
