“[T]he chief excellency of an expounder consists in lucid brevity. And, indeed, since it is almost his only work to lay open the mind of the writer whom he undertakes to explain, the degree in which he leads away his readers from it, in that degree he goes astray from his purpose, and in a manner wanders from his own boundaries. Hence we expressed a hope, that from the number of those who strive at this day to advance the interest of theology by this kind of labour, some one would be found, who would study plainness, and endeavour to avoid the evil of tiring his readers with prolixity. I know at the same time that this view is not taken by all, and that those who judge otherwise have their reasons; but still I cannot be drawn away from the love of what is compendious.”
-John Calvin, taken from the dedication of his Commentary on Romans (http://www.ccel.org/ccel/calvin/calcom38.iii.html)
