We have been told there is one priesthood, and that it has been divided into two parts: the Lower or Levitical, and the High Priesthood (Hebrews 7:11, DoS 5b:1-9). Why this division? It is truly divided?
In the scriptures we are taught to put on the armor of God (see Ephesians 6:10-18). One part of this armor is the Shield of Faith. This is not a metaphorical shield, but a literal shield, a spiritual tool available to use through the power of God; the priesthood.
