[Joseph F. Smith]
... With reference to Prest. B. Youngs remarks, in a discourse delivered in 1852. with reference to "Adam being the only God with whom we have to do" &c. I will say:---Prest. Young no doubt expressed his personal opinion or views upon the subject. What he said was not given as a revelation or commandment from the Lord. The Doctrine was never submitted to the Councils of the Priesthood nor to the Church for approval or ratification and was never formally or otherwise accepted by the Church. ... It is thought, even if there is truth in it, that the bare mention made my Prest. Young, with out indubitable evidence and authority being given of its truth, was unfortunate to say the least.
... When the inspired head, speaks by the power of the spirit & he is backed up by "thus saith the Lord"--, it becomes a serious matter to reject, or lightly pass it by. There is no such responsibility attached to this statement, made by Prest. Young.
