EDITIONS.

1. The earliest important edition is P. Quesnel's (a priest of the Oratory), Paris, 1675, Lyons, 1700. Of this, Migne's Catholic Bibliography Dictionary says, "Father Quesnel’s editions are reproached for a large number of falsifications, by which he intended, in particular, to weaken the papal authority" That is to say, it upheld the Gallican opinions; and so it was condemned and put on the Index in 1632. But being too valuable a work to be altogether suppressed, Benedict XIV enjoined the issue of (4), which rebutted and rectified Quesnel's false deductions in its notes and excurses..
