“ James Ussher, who had become Protestant Primate of Armagh, convoked an assembly of the bishops. They declared that: "The religion of the Papists is superstitious and idolatrous, their church in respect of both, apostatical. To give them, therefore, a toleration, or to consent that they may freely exercise their religion, and profess their faith and doctrine is a grievous sin, and that in two respects. For it is to make ourselves accessory, not only to their superstitions, idolatries, and heresies, and in a word, to all the abominations of Popery ”
