The churches that refused to receive the first angel's message rejected light from heaven. That message was sent in mercy to arouse them to see their true condition of worldliness and backsliding, and to seek a preparation to meet their Lord. SR 364.1
It was to separate the church of Christ from the corrupting influence of the world that the first angel's message was given. But with the multitude, even of professed Christians, the ties which bound them to earth were stronger than the attractions heavenward. They chose to listen to the voice of worldly wisdom, and turned away from the heart-searching message of truth. SR 364.2
God gives light to be cherished and obeyed, not to be despised and rejected. The light which He sends becomes darkness to those who disregard it. When the Spirit of God ceases to impress the truth upon the hearts of men, all hearing is vain, and all preaching also is vain. SR 364.3
When the churches spurned the counsel of God by rejecting the advent message, the Lord rejected them. The first angel was followed by a second, proclaiming, “Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.” Revelation 14:8. This message was understood by Adventists to be an announcement of the moral fall of the churches in consequence of their rejection of the first message. The proclamation, “Babylon is fallen,” was given in the summer of 1844, and as the result, about fifty thousand withdrew from these churches. SR 364.4
Those who preached the first message had no purpose or expectation of causing divisions in the churches, or of forming separate organizations. “In all my labors,” said William Miller, “I never had the desire or thought to establish any separate interest from that of existing denominations, or to benefit one at the expense of another. I thought to benefit all. Supposing that all Christians would rejoice in the prospect of Christ's coming, and that those who could not see as I did would not love any the less those who should embrace this doctrine, I did not conceive there would ever be any necessity for separate meetings. My whole object was a desire to convert souls to God, to notify the world of a coming judgment, and to induce my fellow men to make that preparation of heart which will enable them to meet their God in peace. The great majority of those who were converted under my labors united with the various existing churches. When individuals came to me to inquire respecting their duty, I always told them to go where they would feel at home; and I never favored any one denomination in my advice to such.” SR 365.1
For a time many of the churches welcomed his labors, but as they decided against the advent truth, they desired to suppress all agitation of the subject. Those who had accepted the doctrine were thus placed in a position of great trial and perplexity. They loved their churches, and were loth to separate from them; but as they were ridiculed and oppressed, denied the privilege of speaking of their hope, or of attending preaching upon the Lord's coming, many at last arose and cast off the yoke that had been imposed upon them. SR 365.2
Adventists, seeing that the churches rejected the testimony of God's Word, could no longer regard them as constituting the church of Christ, “the pillar and ground of the truth;” and as the message, “Babylon is fallen,” began to be proclaimed, they felt themselves justified in separating from their former connection. SR 366.1
Since the rejection of the first message, a sad change has taken place in the churches. As truth is spurned, error is received and cherished. Love for God and faith in His Word have grown cold. The churches have grieved the Spirit of the Lord, and it has been in a great measure withdrawn. SR 366.2
