“These last times grow very frequent with some men, till you have the race of clerical visionaries who think vast, dim, vague thoughts, and do no work. It is a danger of all ardent minds. The only salvation, if one finds himself verging to it, is an unsparing rule that no idea, however abstract, shall be every counted as satisfactorily received and grasped till it has opened to us its practical side and helped us somehow in our work”
Phillips Brooks, The Joy of Preaching, p. 77
