First, the mass is a most subtle and pernicious enemy against Christ, and that double, namely, against his priesthood and against his sacrifice. His priesthood is an everlasting priesthood, and such an one as cannot go to another. But the mass utterly puts him out of place, as though he were dead for ever; and so God is forsworn which said Christ should be ‘a priest for ever,’ and Paul lieth which affirmeth Christ to live, and to be ‘on the right hand’ of the Father for us, that by him ‘we may come to the throne of grace to find mercy to help us in our need:’ for, if these be true as they be most true, the mass priests are to be put down: for, if they be ‘of the order of Aaron,’ then resume they that which Christ hath abolished; if they be ‘of the order of Melchisedec,’ then be they Christ’s. Other orders of priests I read none, save that which all Christians be, to offer up themselves to God and other spiritual sacrifices by Christ, and the order of ‘priests of Baal,’ whose successors indeed the massers be (from The Writings of John Bradford, volume 2, pp. 312-313).
