De Ebrietate

Do then therefore pray to God never to begin revelry or drunkenness, that is to say, never intentionally to set forth in the road which leads to ignorance and folly; for unintentional errors are as light again as deliberate sins, inasmuch as they are not weighed down by the irresistible conviction of conscience.

And when your prayers have been accomplished, you will no longer be able to remain in ignorance or out of office, but you will acquire the most important of all offices, namely, the priesthood. For it is almost the only occupation of the priests and ministers of God to offer abstemious sacrifices, abstaining in the firmness of their minds from wine and from every other cause of folly.

For, says the scripture, "The Lord spoke unto Aaron, saying, Wine and strong drink shalt thou not drink, neither thou nor thy sons after thee, when ye come into the tabernacle of the testimony, or when ye approach the altar of sacrifice, so that ye may not die. This shall be an everlasting law for all your generations to distinguish between what is sacred and what is profane, and between what is pure and what is impure." [*](Leviticus x. 8. )

But Aaron is the priest, and the interpretation of his name is "mountainous;" reasoning occupying itself with sublime and lofty objects, not on account of the superabundant excess of the arrogance of empty pride, but by reason of the magnitude [*](Leviticus x. 8. )
