"There are many seeming contradictions and even obscurities in the innumerable writings of the church fathers. Our respect for their authority should not stand in the way of an effort on our part to come at the truth. The obscurity and contradictions in ancient writings may be explained upon many grounds, and may be discussed without impugning the good faith and insight of the fathers. A writer may use different terms to mean the same thing, in order to avoid a monotonous repetition of the same word. Common, vague words may be employed in order that the common people may understand; and sometimes a writer sacrifices perfect accuracy in the interest of a clear general statement. Poetical, figurative language is often obscure and vague. Not infrequently apocryphal works are attributed to the saints. Then, even the best authors often introduce the erroneous views of others and leave the reader to distinguish between the true and the false. Sometimes, as Augustine confesses in his own case, the fathers ventured to rely upon the opinions of others."
