"It has always been hard to recognize in fallible human beings the authorized servants of God. Paul must have seemed an ordinary man to many. Joseph Smith's cheerful disposition was seen by some as not fitting their expectations for a prophet of God.
"Satan will always work on the Saints of God to undermine their faith in priesthood keys. One way he does it is to point out the humanity of those who hold them. He can in that way weaken our testimony and so cut us loose from the line of keys by which the Lord ties us to Him."
--Henry B Eyring, "Faith and Keys," Ensign, November 2004, 28
