a very serious conversation took place between Prest B Young and Orson Pratt upon doctrine.
O. P. was directly opposed to the Prest views and very freely expressed his entire disbelief in them after being told by the President that things were so and so in the name of the Lord.
He was firm in the Position that the Prest's word in the name of the Lord, was not the word of the Lord to him.
The Prest did not believe that Orson would ever be Adam, to learn by experience the facts discussed, but every other person in the room would if they lived faithful.
