"And there was some trouble with Oliver Cowdery, and whisper said it was relating to a girl then living in his family; and I was afterwards told by Warren Parish, that he himself and Oliver Cowdery did not that Joseph had Fannie Alger as wife, for they were spied upon and found together. And I can now see that at Nauvoo, so at Kirtland, that the suspicion or knowledge of the Prophet's plural relation was one of the causes of apostasy and disruption at Kirtland, although at the time there was little said publicly on the subject."

What kind of authority can there be for an 'Apostle' who, unlike the other Apostles, had never been prepared for the Apostolic office in Jesus' own school but had only later dared to claim the Apostolic office on the basis of his own authority? The only question comes to be how the apostle Paul appears in his Epistles to be so indifferent to the historical facts of the life of Jesus....He bears himself but little like a disciple who has received the doctrines and the principles which he preaches from the Master whose name he bears.
