transubstantiation, of which, says bishop Burnet, “the Latin style is better than the divinity.” The labours of one who exerted himself to overthrow what the bishop wished to support, could not {83} fail to be very disagreeable to Tonstal. As Knox acted under the authority of the protector and council, he durst not inhibit him; but he was disposed to listen to the informations which were lodged against him by the clergy. Although the town of Berwick was Knox’s principal station during the years 1549 and 1550, it is probable that he was appointed to preach occasionally in the adjacent country. Whether, in the course of his itinerancy, he had preached in Newcastle, or whether he was called up to it in consequence of complaints against the sermons which he had delivered at Berwick, it is difficult to ascertain. It is, however, certain, that a charge was exhibited against him before the bishop, for teaching that the sacrifice of the mass was idolatrous, and that a day was appointed for him publicly to assign his reasons for this opinion. Accordingly, on the 4th of April, 1550, a large assembly being convened in Newcastle, among whom were the members of the council,[119] the bishop of Durham, and the learned men of his cathedral, Knox delivered in their presence an ample defence of his doctrine. After an appropriate exordium, in which he stated to the audience the occasion and design of his appearance, and cautioned them against the powerful {84} prejudices of education and custom in favour of erroneous opinions and corrupt practices in religion, he proceeded to establish the doctrine which he had taught. The manner in which he treated the subject was well adapted to his auditory, which was composed both of the learned and the illiterate. He proposed his arguments in the syllogistic form, according to the practice of the schools, but illustrated them with a plainness level to the meanest capacity among his hearers. The propositions on which he rested his defence are very descriptive of his characteristic boldness of thinking and acting. A more cautious and timid disputant would have satisfied himself with attacking the grosser notions which were generally entertained by the people on this subject, and exposing the glaring abuses of which the priests were guilty in the lucrative sale of masses. Knox scorned to occupy himself in demolishing these feeble and falling outworks, and proceeded directly to establish a principle which overthrew the whole fabric of superstition. He engaged to prove that the mass, “even in her most high degree,” and when stripped of the meretricious dress in which she now appeared, was an idol struck from the inventive brain of superstition, which had supplanted the sacrament of the supper, and engrossed the honour due to the person and sacrifice of Jesus Christ. “Spare no arrows,” was Knox’s motto; the authority of scripture, and the force of reasoning, grave reproof, and pointed irony, were weapons
