9 The duties of his office he discharged in the same spirit as that in which he had been preferred to it. For he did not at once, after taking possession of his throne, like men who have unexpectedly seized upon some sovereignty or inheritance, grow insolent from intoxication. This is the conduct of illegitimate and intrusive priests, who are unworthy of their vocation; whose preparation for the priesthood has cost them nothing, who have endured no inconvenience for the sake of virtue, who only begin to study religion when appointed to teach it, and undertake the cleansing of others before being cleansed themselves; yesterday sacrilegious, today sacerdotal; yesterday excluded from the sanctuary, today its officiants; proficient in vice, novices in piety; the product of the favour of man, not of the grace of the Spirit; who, having run through the whole gamut of violence, at last tyrannize over even piety; who, instead of gaining credit for their office by their character, need for their character the credit of their office, thus subverting the due relation between them; who ought to offer more sacrifices for themselves than for the ignorances of the people; who inevitably fall into one of two errors, either, from their own need of indulgence, being excessively indulgent, and so even teaching, instead of checking, vice, or cloaking their own sins under the harshness of their rule. Both these extremes he avoided; he was sublime in action, lowly in mind; inaccessible in virtue, most accessible in intercourse; gentle, free from anger, sympathetic, sweet in words, sweeter in disposition; angelic in appearance, more angelic in mind; calm in rebuke, persuasive in praise, without spoiling the good effect of either by excess, but rebuking with the tenderness of a father, praising with the dignity of a ruler, his tenderness was not dissipated, nor his severity sour; for the one was reasonable, the other prudent, and both truly wise; his disposition sufficed for the training of his spiritual children, with very little need of words; his words with very little need of the rod, and his moderate use of the rod with still less for the knife.
