A briefe apologie, or defence of the Catholike ecclesiastical hierarchie, and subordination in England, erected these later yeeres by our holy father Pope Clement the eight; and impugned by certaine libels printed and published of late both in Latine and English; by some vnquiet persons vnder the name of priests of the seminaries. Written and set forth ... by priestes vnited in due subordination, to the Right Reuerend Archpriest, and other their superiors. [By Robert Persons.]
