What diversity there ought to be in the art of preaching.
Differently to be admonished are these that follow:
Men and women.
The poor and the rich.
The joyful and the sad.
Prelates and subordinates.
Servants and masters.
The wise of this world and the dull.
The impudent and the bashful.
The forward and the fainthearted.
The impatient and the patient.
The kindly disposed and the envious.
The simple and the insincere.
The whole and the sick.
Those who fear scourges, and therefore live innocently; and those who have grown so hard in iniquity as not to be corrected even by scourges.
The too silent, and those who spend time in much speaking.
The slothful and the hasty.
The meek and the passionate.
The humble and the haughty.
The obstinate and the fickle.
The gluttonous and the abstinent.
Those who mercifully give of their own, and those who would fain seize what belongs to others.
Those who neither seize the things of others nor are bountiful with their own; and those who both give away the things they have, and yet cease not to seize the things of others.
Those that are at variance, and those that are at peace.
Lovers of strifes and peacemakers.
Those that understand not aright the words of sacred law; and those who understand them indeed aright, but speak them without humility.
Those who, though able to preach worthily, are afraid through excessive humility; and those whom imperfection or age debars from preaching, and yet rashness impels to it.
Those who prosper in what they desire in temporal matters; and those who covet indeed the things that are of the world, and yet are wearied with the toils of adversity.
Those who are bound by wedlock, and those who are free from the ties of wedlock.
Those who have had experience of carnal intercourse, and those who are ignorant of it.
Those who deplore sins of deed, and those who deplore sins of thought.
Those who bewail misdeeds, yet forsake them not; and those who forsake them, yet bewail them not.
Those who even praise the unlawful things they do; and those who censure what is wrong, yet avoid it not.
Those who are overcome by sudden passion, and those who are bound in guilt of set purpose.
Those who, though their unlawful deeds are trivial, yet do them frequently; and those who keep themselves from small sins, but are occasionally whelmed in graver ones.
Those who do not even begin what is good, and those who fail entirely to complete the good begun.
Those who do evil secretly and good publicly; and those who conceal the good they do, and yet in some things done publicly allow evil to be thought of them.
But of what profit is it for us to run through all these things collected together in a list, unless we also set forth, with all possible brevity, the modes of admonition for each?
(Admonition 1.) Differently, then, to be admonished are men and women; because on the former heavier injunctions, on the latter lighter are to be laid, that those may be exercised by great things, but these winningly converted by light ones.
(Admonition 2.) Differently to be admonished are young men and old; because for the most part severity of admonition directs the former to improvement, while kind remonstrance disposes the latter to better deeds. For it is written, Rebuke not an elder, but entreat him as a father.
