There is a quote, attributed to Brigham Young, and used by many dissidents, in the Church and out, to create doubt in the words of living Prophets:
“The greatest fear I have is that the people of this Church will accept what we say as the will of the Lord without first praying about it and getting the witness within their own hearts that what we say is the word of the Lord.” – Brigham Young
I have seen and heard this quote numerous times from people who preach that we must be careful to not take the things prophets teach at face-value. They suggest that every word a prophet speaks must be challenged and considered before it is accepted as the word of God. It appears to be a tactic to take away some of the power of scriptural revelations such as:
What I the Lord have spoken, I have spoken, and I excuse not myself; and though the heavens and the earth pass away, my word shall not pass away, but shall all be fulfilled, whether by mine own voice or by the voice of my servants, it is the same. (D&C 1:38)
Here is a real shocker!!
The quote is not from Brigham Young. It is not correct. And it is not the doctrine of The Church of Jesus Christ of Latter-day Saints.
A fine young man who was disturbed by continual reference to the quote did some research and discovered the genesis of the message.
His post is rather lengthy (for obvious reasons you will see) but very useful in debunking the false teachings of those who would cast doubt on the words of living prophets.
Prophets are fallible and can make errors in judgment concerning many things. But when they speak by the power of the Holy Ghost, they are speaking the words of Christ. Our response is not to doubt, but to confirm the message using the same method by which the message was given.
This truth is the kind that you can rely on in all circumstances. Of course, you will need to have a testimony of prophets and apostles before it will make sense.
