Journal of Discourses 18:215-216; “There are only two churches on the earth—only two parties. God leads the one, the devil the other. As soon as a man hears the Gospel preached and becomes convinced of this truthfulness, he is tempted of the devil, who, whenever there is an opportunity, suggests doubt for his reflection…This single doubt is perhaps the beginning of his apostacy [sic] from the Church. In the days of Joseph, people were inclined to turn away from the faith and go into apostacy [sic], as much as they do to in proportion to our numbers, and I have sometimes thought more so. You allow the devil to suggest to you that I am not leading you right, and allow that thought to abide in your hearts, and I will promise you that it will lead you to apostacy [sic]. You allow yourselves to doubt anything that God has revealed, and it will not be a great while before you begin to neglect your prayers, refuse to pay your Tithing, and find fault with the authorities of the Church.” – Brigham Young, Logan, Utah, August 15, 1876.
2 Timothy 2:19; “Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.”
When the Mormons tell you that Smith, Young or any of the other leaders were only speaking of the Catholic Church as being the “whore of Babylon”, you now have proof that theory is false.
