The Spirit of Prophecy Volume Four
The Loud Cry
As the storm approaches, a large class who have professed faith in the third message, but have not been sanctified through it, abandon their position, and take refuge under the banner of the powers of darkness. By uniting with the world and partaking of its spirit, they come to view matters in nearly the same light; and when the test is brought, they are prepared to choose the easy, popular side. Men of talent and pleasing address, who once rejoiced in the truth, employ their powers to deceive and mislead souls. They become the most bitter enemies of their former brethren. When Sabbath-keepers are brought before the courts to answer for their faith, these apostates are the most efficient agents of Satan to misrepresent and accuse them, and by false reports and insinuations to stir up the rulers against them.
They professed faith in the message, that is that Truth reigns supreme over error, abandon their position of holding Truth Supreme over False theories and Traditions.
They show forth the sentiment "When in Rome, do as the Romans" and thus show they love this world and it's friendship more than Supreme Love and Homage to The Most High, which will bring reproach and persecution as they obey All His Divine Precepts and Statutes and Judgements.
"As the storm approaches"
means the conflict over the True and False sabbath, that is the calendar which calls forth the weekly cycles.
