were not indifferent, since they obscured the priesthood of Christ by encouraging hypocrisy and superstition. Warwick disagreed, emphasising that the king must be obeyed in things indifferent, and he pointed to St Paul's concessions to Jewish traditions in the early church. Finally, an acrimonious debate with Ridley went against Hooper. Ridley's position centred on maintaining order and authority; not the vestments themselves, Hooper's primary concern. Biblical texts cited in this and subsequent debates—and the ways in which they were interpreted—came to be defining features of conservative and puritan Protestant discourse. They were echoed elsewhere, such as the famous glosses of the Geneva Bible. Hooper–Ridley debate In a Latin letter dated October 3, 1550, Hooper laid out his argument contra usum vestium. He argued that vestments should not be used as they are not indifferent, nor is their use supported by scripture. He contends that church practices must either have express biblical support or be things indifferent, approval for which is implied by scripture. He then all but excludes the possibility of anything being indifferent in the four conditions he sets: Hooper cites Romans 14:23b (whatsoever is not of faith is sin), Romans 10:17 (faith cometh from hearing, and hearing by the word of God), and Matthew 15:13 (every plant not planted by God will be rooted up) to argue that indifferent things must be done in faith, and since what cannot be proved from scripture is not of faith, indifferent things must be proved from scripture, which is both necessary and sufficient authority, as opposed to tradition. He maintains that priestly garb distinguishing clergy from laity is not indicated by scripture; there is no mention of it in the New Testament as being in use in the early church, and the use of priestly clothing in the Old Testament is a Hebrew practice, a type or foreshadowing that finds its antitype in Christ, who abolishes the old order and recognises the spiritual equality, or priesthood, of all Christians. The historicity of these claims is supported by reference to Polydore Vergil's De Inventoribus Rerum. In response, Ridley rejected Hooper's insistence on biblical origins and countered Hooper's interpretations of his chosen biblical texts. He pointed out that many non-controversial practices are not mentioned or implied in scripture. Ridley denied that early church practices are normative for the present situation, and he linked such arguments with the Anabaptists. Ridley joked that Hooper's reference
