On the Creation of Magistrates (1.121-1.125)

For if in merchant vessels the sailors were to receive an equal share with the pilot of the ship, and if in ships of war the rowers and the mariners were to receive an equal share with the captain, and if in military camps the cavalry of the line were to receive an equal share with their officers, the heavy armed infantry with their colonels, and the colonels with the generals; again, if in cities the parties before the court were to be placed on the same footing with the judges, the committeemen with the ministers, and in short private individuals with the magistrates, there would be incessant troubles and seditions, and the equality in words would produce inequality in fact; for it is an unequal measure to give equal honour to persons who are unequal in rank or desert; and inequality is the root of all evil.

On which account one must not give the honours of the priests to sojourners, just as one must not give them to any one else, who in that case, [*] [*]

In like manner, no one must give this sacred honour to a hireling, as his wages, or as a recompense for his service; for sometimes he who receives it being unholy will employ it for illegitimate purposes, making the honours due to purity of birth common, and profaning all the sacred ceremonies and observances relating to the temple;

on which account the law altogether forbids any foreigner to partake in any degree of the holy things, even if he be a man of the noblest birth among the natives of the land, and irreproachable as respects both men and women, in order that the sacred honours may not be adulterated, but may remain carefully guarded in the family of the priests;

for it would be absurd that the sacrifices and holy ordinances, and all the other sacred observances pertaining to the altar, should be entrusted not to all men but to the priests alone; but that the rewards for the performance of those things should be common and liable to fall to the share of any chance persons, as if it were reasonable that the priests should be worn out with labours and toils, and nightly and daily cares, but that the rewards for such pains should be common and open to those who do nothing.
