James Talmage gives an evidence of the Great Apostasy:
> “Disregard for truth. As early as the fourth century, certain pernicious doctrines embodying a disregard for truth gained currency in the Church. Thus, it was taught ‘that it was an act of virtue to deceive and lie, when by that means the interests of the church might be promoted.’—(Mosheim, ‘Eccl. Hist.,’ Cent. IV, Part II, ch. 3:16.) Needless to say, sins other than those of falsehood and deceit were justified when committed in the supposed interests of church advancement, and crime was condoned under the specious excuse that the end justifies the means. Many of the fables and fictitious stories relating to the lives of Christ and the apostles, as also the spurious accounts of supernatural visitations and wonderful miracles, in which the literature of the early centuries abound, are traceable to this infamous doctrine that lies are acceptable unto God if perpetrated in a cause that man calls good.” (James Talmage, The Great Apostasy, ch. 7)
It’s a good thing Mormonism doesn’t do that kind of thing, right? Otherwise, that’d be an evidence of apostasy.
PS It might sound like Talmage is quoting an early church father, but he’s not. He is quoting the historian Johann Lorenz von Mosheim.
