Christians need to learn the tools of Rhetoric both to persuade and to gain wisdom and understanding of our times. “Since, then, the faculty of eloquence is available for both sides, and is of very great service in the enforcing either of wrong or right, why do not good men study to engage it on the side of truth, when bad men use it to obtain the triumph of wicked and worthless causes, and to further injustice and error?” —Augustine, On Christian Teaching (quoted in Fitting Words: Classical Rhetoric for the Christian Student by James B Nance).
