Letter 73
VIII,1. Nor do we propose this, dearest brother, without the authority of divine Scripture, when we say that all things are arranged by divine direction by a certain law and by special ordinance, and that none can usurp to himself, in opposition to the bishops and priests, anything which is not of his own right and power. For Korah, Dathan, and Abiram endeavoured to usurp, in opposition to Moses and Aaron the priest, the power of sacrificing; and they did not do without punishment what they unlawfully dared.
2. The sons of Aaron also, who placed strange fire upon the altar, were at once consumed in the sight of an angry Lord; which punishment remains to those who introduce strange water by a false baptism, that the divine vengeance may avenge and chastise when heretics do that in opposition to the Church, which the Church alone is allowed to do.
