The consecration of priests in Yahwism is a special ritual. It is connected with the understanding of sacrifice characteristic of the Yahwist tradition, and with the corresponding understanding of holiness. Holiness in Yahwism means above all participation in that presence of God which was revealed to Moses on Sinai and which afterward accompanied the people along the whole path of their earthly history.
The priesthood was established so that among God's people there would always, at every moment, be some group of people remaining in a state of consecration and standing by the altar, in the place of God's presence, literally physically. The rites of consecration for priests described in the Book of Exodus were needed in order to introduce the priests, who were to serve God directly, into that spiritual space where communion with God was an everyday reality.
Before the coming of Christ, such a state was not an ordinary thing for a person, as it is for us today. Today we live in a world to which the Kingdom, in the Savior's words, has "drawn near," drawn so near that its breath is felt everywhere and everyone who cares about it can come into contact with it. But then, in the time of Moses, when almost fifteen centuries still remained before the coming of Christ, everything was different.
Direct communion with God was then the exception rather than the rule. It was given rarely and to few people, and besides, at the cost of great effort. God's dwelling among His people was the single exception, an enormous possibility open to everyone who belonged to the people; but one could make use of this possibility only by making the corresponding effort. One had to change one's life completely, to live only for this Presence and to live only by it.
In those times only a few could live such a life; it required special spiritual strength, and the consecration of priests for service was meant to give them that strength. Here, of course, there was no automatism and no magic. In order really to receive the strength needed for service, it was necessary to turn to God, to establish with Him the relationships that would allow Him to interact with the one being consecrated. The possibility of such consecration existed; whether to make use of it or not depended on the one being consecrated.
