The most definite instructions on this subject are found in the Book of Mormon. When the Nephite disciples of Jesus were, at a certain time, united in mighty prayer and fasting, he came and stood in the midst of them, and asked them, "What will ye that I shall give unto you?" "And they said unto him, Lord, we will that thou wouldst tell us the name whereby we shall call this church; for there are disputations among the people concerning this matter.
"And the Lord said unto them, Verily, verily I say unto you, why is it that the people should murmur and dispute because of this thing? Have they not read the scriptures, which say ye must take upon you the name of Christ, which is my name? For by this name shall ye be called at the last day; and whoso taketh upon him my name, and endureth to the end, the same shall be saved at the last day; therefore whatsoever ye shall do, ye shall do it in my name; therefore ye shall call the church in my name; and ye shall call upon the Father in my name, that he will bless the church for my sake; and how be it my church, save it be called in my name? For if a church be called in Moses' name, then it be Moses' church; or if it be called in the name of a man, then it be the church of a man; but if it be called in my name, then it is my church, if so be that they are built upon my Gospel;" 3 Nephi 27. 2-8.
In accordance with the spirit of the Old and New Testaments, and with these instructions of Jesus Christ, when the church was organized on Gospel principles, by Joseph Smith, Jun., in 1830, it was named, "The Church of Jesus Christ." The Lord afterwards revealed to his Prophet, Joseph Smith, that it should be called, "The Church of Jesus Christ of Latter-day Saints;" Doc. & Cov. 115. 3, 4.

TITHING.
The history of ancient Israel, as given in the Old Testament, evidences that the law of tithing was in force from Abraham until their destruction as a nation. That it was a perpetual law of the Priesthood, and did not pertain, exclusively, to the Mosaic dispensation, is apparent, from the fact that Abram paid tithes to Melchisedek; Gen. 14. 20, and that Jacob covenanted to give a tenth to the Lord; 28. 22. They lived before Moses.
