God's word has given warning of the impending danger; let this be unheeded, and the Protestant world will learn what the purposes of Rome really are, only when it is too late to escape the snare. She is silently growing into power. Her doctrines are exerting their influence in legislative halls, in the churches, and in the hearts of men. She is piling up her lofty and massive structures in the secret recesses of which her former persecutions will be repeated. Stealthily and unsuspectedly she is strengthening her forces to further her own ends when the time shall come for her to strike. All that she desires is vantage ground, and this is already being given her. We shall soon see and shall feel what the purpose of the Roman element is. Whoever shall believe and obey the word of God will thereby incur reproach and persecution.
