I was doing some research this morning when I stumbled upon a very interesting passage from a book published in 1916 by Levi Rightmyer entitled, The Light of Truth as Revealed in the Holy Scriptures. The entire text of the book is available for perusal on Google Books here. The author is not LDS, although he appears to have known something of the Church (see page 482 for his reference to “Joseph Smith and the Mormons of Utah”).
What I found was a passage which discusses Christ, a priest after the order of Melchizedek, and that “all who are called to God’s kingdom and glory are called to fill the positions of Melchisedec kings and priests in the ages to come under the Lord Jesus Christ…” and if this truth is not so today it is because of apostasy:
…mankind have been deceived by false and ignorant teachers who in the early days of the church corrupted the way of the Lord as the antediluvian sons of God did before the flood, who walked after the vain imaginations of their own evil hearts even as it is now. The world is full of religion, but nearly empty of the true knowledge of God. There are many great revivals in which are developed a high degree of religious feeling, but unfortunately they are attended with a very low degree of scriptural knowledge and true religious intelligence.
