And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel. And a holy nation - They should be a nation, one people; firmly united among themselves, living under their own laws; and powerful, because united, and acting under the direction and blessing of God. They should be a holy nation, saved from their sins, righteous in their conduct, holy in their hearts; every external rite being not only a significant ceremony, but also a means of conveying light and life, grace and peace, to every person who conscientiously used it. Thus they should be both a kingdom, having God for their governor; and a nation, a multitude of peoples connected together; not a scattered, disordered, and disorganized people, but a royal nation, using their own rites, living under their own laws, subject in religious matters only to God, and in things civil, to every ordinance of man for God's sake.
This was the spirit and design of this wonderful institution, which could not receive its perfection but under the Gospel, and has its full accomplishment in every member of the mystical body of Christ.
