111 For if it be granted, and this alone can be strongly asserted in such matters, that we are far too low to perform the priest's office before God, and that we can only be worthy of the sanctuary after we have become worthy of the Church, and worthy of the post of president, after being worthy of the sanctuary, yet some one else may perhaps refuse to acquit us on the charge of disobedience. Now terrible are the threatenings against disobedience, and terrible are the penalties which ensue upon it; as indeed are those on the other side, if, instead of being reluctant, and shrinking back, and concealing ourselves as Saul did among his father's stuff — although called to rule but for a short time— if, I say, we come forward readily, as though to a slight and most easy task, whereas it is not safe even to resign it, nor to amend by second thoughts our first.
