Well of course it is not just a testimony against mormonism but it certainly seems at times to have been written with Joseph Smith in mind. I was struck by this again tonight as we read in Hebrews 7 at the gathering of the church, especially here:
The former priests were many in number, because they were prevented by death from continuing in office, but he holds his priesthood permanently, because he continues forever. (Heb 7:23-24)
Notice the contrast between a priesthood of Aaron that served in the temple that required many members and the priesthood after the order of Melchizedek that only Christ holds. Of particular note here and throughout the book of Hebrews is the difference between the priesthood of Aaron with many priests and the priesthood of Melchizedek which is always spoken of exclusively referencing Christ in the singular. There is only One who holds this priesthood and His name is Jesus Christ. The smiling young men in dark suits and white dress shirts going door to door and the men who claim to be bishops in a restored church and the old guys in Salt Lake City who declare themselves "apostles" all have blasphemously and presumptuously declared that they share in a priesthood that is reserved for our Great High Priest Jesus Christ and Him alone. By claiming the priesthood that only Jesus Christ can hold these men place themselves on equal footing with Jesus Christ. Providentially the Bible recorded the refutation of the false notion of a "Melchizedek priesthood" with millions of holders long before Joseph Smith concocted his heretical story of ghosts giving him a priesthood that no mere man can hold. I have placed and will continue to place my hope and assurance in Jesus Christ and His priesthood and not in the pale shadow and mockery instituted by Joseph Smith.
