Yet this very class put forth the claim that the fast-spreading corruption is largely attributable to the desecration of the so-called “Christian Sabbath,” and that the enforcement of Sunday observance would greatly improve the morals of society. This claim is especially urged in America, where the doctrine of the true Sabbath has been most widely preached. Here the temperance work, one of the most prominent and important of moral reforms, is often combined with the Sunday movement, and the advocates of the latter represent themselves as laboring to promote the highest interest of society; and those who refuse to unite with them are denounced as the enemies of temperance and reform. But the fact that a movement to establish error is connected with a work which is in itself good, is not an argument in favor of the error. We may disguise poison by mingling it with wholesome food, but we do not change its nature. On the contrary, it is rendered more dangerous, as it is more likely to be taken unawares. It is one of Satan's devices to combine with falsehood just enough truth to give it plausibility. The leaders of the Sunday movement may advocate reforms which the people need, principles which are in harmony with the Bible; yet while there is with these a requirement which is contrary to God's law, His servants cannot unite with them. Nothing can justify them in setting aside the commandments of God for the precepts of men. DD 32.1
Through the two great errors, the immortality of the soul and Sunday sacredness, Satan will bring the people under his deceptions. While the former lays the foundation of spiritualism, the latter creates a bond of sympathy with Rome. The Protestants of the United States will be foremost in stretching their hands across the gulf to grasp the hand of spiritualism; they will reach over the abyss to clasp hands with the Roman power; and under the influence of this threefold union, this country will follow in the steps of Rome in trampling on the rights of conscience.

As spiritualism more closely imitates the nominal Christianity of the day, it has greater power to deceive and ensnare. Satan himself is converted, after the modern order of things. He will appear in the character of an angel of light. Through the agency of spiritualism, miracles will be wrought, the sick will be healed, and many undeniable wonders will be performed. And as the spirits will profess faith in the Bible, and manifest respect for the institutions of the church, their work will be accepted as a manifestation of divine power.... DD 33.1
