In an address on "Biography," delivered at Phillips Exeter Academy, he said that he would rather have written a great biography than any other great book.
The "Lectures on Preaching" abound, like all his work, in short, concise sentences full of meaning, and should be read especially by every one who intends to preach.
He tells young men that the talk about prevalent aversion to hearing the gospel is foolish. "The age," he says, "has no aversion to preaching as such. It may not listen to your preaching. If that prove to be the case, look for the fault first in your preaching, and not in the age. I wonder at the eagerness and patience of congregations.... Never fear, as you preach, to bring the sublimest motive to the smallest duty, and the most infinite comfort to the smallest trouble."
The necessary qualities in a preacher, Phillips Brooks thinks, are, "Personal piety,—nothing but fire kindles fire,"—hopefulness; such physical condition as comes from a due regard to health; enthusiasm; "the quality that kindles at the sight of men, that feels a keen joy at the meeting of truth and the human mind."
First among the elements of power, Phillips Brooks puts "personal uprightness and purity." "No man permanently succeeds in the ministry who cannot make men believe that he is pure and devoted; and the only sure and lasting way to make men believe in one's devotion and purity is to be what one wishes to be believed to be." He said. "No man can do much for others who is not much himself.... The priest must be the most manly of all men."
The second element of power is "freedom from self-consciousness." "No man ever yet thought whether he was preaching well without weakening his sermon."
The third element is "genuine respect for the people whom he preaches to." "There is no good preaching in the supercilious preacher."
The fourth is "gravity." Dr. Brooks thinks the "merely solemn ministers are very empty ... cheats and shams;" but thinks the "clerical jester" merits "the contempt of Christian people." "He is full of Bible jokes.... There are passages in the Bible which are soiled forever by the touches which the hands of ministers who delight in cheap and easy jokes have left upon them.... Refrain from all joking about congregations, flocks, parish visits, sermons, the mishaps of the pulpit, or the makeshifts of the study. Such joking is always bad, and almost always stupid; but it is very common, and it takes the bloom off a young minister's life." Dr. Brooks was especially careful in remarks about any person.
The fifth element of power is "courage." "If you are afraid of men, and a slave to their opinion, go and do something else. Go and make shoes to fit them."
Phillips Brooks then turns to the dangers which beset young preachers. The first is self-conceit. "He who lives with God must be humble," he has said in his sermon, "How to Abound." Another danger is narrowness. Still another is self-indulgence. "We are apt to become men of moods, thinking we cannot work unless we feel like it.... The first business of the preacher is to conquer the tyranny of his moods, and to be always ready for his work. It can be done.... Resent indulgences which are not given to men of other professions. Learn to enjoy and be sober; learn to suffer and be strong. Never appeal for sympathy."
