Edward Bok's lines were now to follow those of advertising for several years. He was responsible for securing the advertisements for The Book Buyer and The Presbyterian Review. While the former was, frankly, a house-organ, its editorial contents had so broadened as to make the periodical of general interest to book-lovers, and with the subscribers constituting the valuable list of Scribner book-buyers, other publishers were eager to fish in the Scribner pond.
With The Presbyterian Review, the condition was different. A magazine issued quarterly naturally lacks the continuity desired by the advertiser; the scope of the magazine was limited, and so was the circulation. It was a difficult magazine to "sell" to the advertiser, and Bok's salesmanship was taxed to the utmost. Although all that the publishers asked was that the expense of getting out the periodical be met, with its two hundred and odd pages even this was difficult. It was not an attractive proposition.
The most interesting feature of the magazine to Bok appeared to be the method of editing. It was ostensibly edited by a board, but, practically, by Professor Francis L. Patton, D.D., of Princeton Theological Seminary (afterward president of Princeton University), and Doctor Charles A. Briggs, of Union Theological Seminary. The views of these two theologians differed rather widely, and when, upon several occasions, they met in Bok's office, on bringing in their different articles to go into the magazine, lively discussions ensued. Bok did not often get the drift of these discussions, but he was intensely interested in listening to the diverse views of the two theologians.
One day the question of heresy came up between the two men, and during a pause in the discussion, Bok, looking for light, turned to Doctor Briggs and asked: "Doctor, what really is heresy?"
Doctor Briggs, taken off his guard for a moment, looked blankly at his young questioner, and repeated: "What is heresy?"
"Yes," repeated Bok, "just what is heresy, Doctor?"
"That's right," interjected Doctor Patton, with a twinkle in his eyes, "what is heresy, Briggs?"
"Would you be willing to write it down for me?" asked Bok, fearful that he should not remember Doctor Briggs's definition even if he were told.
And Doctor Briggs wrote:
"Heresy is anything in doctrine or practice that departs from the mind of the Church as officially defined.
