The Everlasting Covenant
The Oath and the Priesthood
The oath of God confirmed the covenant. The oath by which the promise was confirmed gives us strong consolation when we flee for refuge to the sanctuary where Christ is priest in our behalf, after the order of Melchizedek. EVCO 109.5
Therefore that oath was the same as the oath that made Christ priest for ever after the order of Melchizedek. This is clearly set forth in the statement that Christ was made priest “with an oath by Him that said unto Him, The Lord sware, and will not repent. Thou art a priest for ever after the order of Melchizedek” 1 and that He is able therefore to save them to the uttermost that come to God by Him. EVCO 110.1
