Jacob 5:35

35 And it came to pass that the Lord of the vineyard said unto his servant: The tree profiteth me nothing, and the roots of the tree profit me nothing so long as it shall bring forth evil fruit.

Article of Faith 6

6. We believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists, and so forth.

Gordon B. Hinckley (April 1995 Conference)

This church does not belong to its President. Its head is the Lord Jesus Christ, whose name each of us has taken upon ourselves. We are all in this great endeavor together. We are here to assist our Father in His work and His glory, "to bring to pass the immortality and eternal life of man." (Moses 1:39) Your obligation is as serious in your sphere of responsibility as is my obligation in my sphere. No calling in this church is small or of little significance. All of us in the pursuit of our duty touch the lives of others...

You have as great an opportunity for satisfaction in the performance of your duty as I do in mine. The progress of this work will be determined by our joint efforts. Whatever your calling, it is fraught with the same kind of opportunity to accomplish good as is mine. What is really important is that this is the work of the Master. Our work is to go about doing good as did He.
