“…this missal is hereafter to be followed absolutely, without any scruple of conscience or fear of incurring any penalty, judgment or censure, and may freely and lawfully be used… Nor are superiors, administrators, canons, chaplains, and other secular priests, or religious, of whatever title designated, obliged to celebrate the Mass otherwise than as enjoined by Us. … Accordingly, no one whatsoever is permitted to infringe or rashly contravene this notice of Our permission, statute, ordinance, command, precept, grant, direction, will, decree and prohibition. Should any person venture to do so, let him understand he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul.”
