[233] See his Commentary on St. Luke (xxii. 19, 20.) [234] He added, that the body of Christ was in the Eucharist neither mathematically or commensurably, nor really (neque mathematice seu commensurative, neque re ipsa).--(Epist. Lamb. de Marb. col.) Luther was, however, by no means shaken. "_This is my body_," repeated he, pointing with his finger to the words written before him. "_This is my body._ The devil himself shall not drive me from that. To seek to understand it, is to fall away from the faith."[235] [235] Si interrogo, excido a fide.--(Zw. Epp. ii. p. 177.) "But, doctor," said Zwingle, "St. John explains how Christ's body is eaten, and you will be obliged at last to leave off singing always the same song." [Sidenote: AGITATION IN THE CONFERENCE.] "You make use of unmannerly expressions," replied Luther[236]. The Wittembergers themselves called Zwingle's argument "his old song."[237] Zwingle continued without being disconcerted: "I ask you, doctor, whether Christ in the sixth chapter of St. John did not wish to reply to the question that had been put to him?" [236] Invidiose loqueris.--(Bull. ii. p. 228.) [237] Veterem suam cantilenam.--(Zw. Opp. iv. p. 221.) LUTHER.--"Mr. Zwingle, you wish to stop my mouth by the arrogancy of your language. That passage has nothing to do here." ZWINGLE, hastily.--"Pardon me, doctor, that passage breaks your neck." LUTHER.--"Do not boast so much! You are in Hesse, and not in Switzerland. In this country we do not break people's necks." Then turning towards his friends, Luther complained bitterly of Zwingle; as if the latter had really wished to break his neck. "He makes use of soldier-like and blood-stained words," said he.[238] Luther forgot that he had employed a similar expression in speaking of Carlstadt.[239] [238] Verbum istud, tanquam castrense et cruentum.--(Hospin. p. 131.) [239] Vol. III. Book ix. ZWINGLE resumed: "In Switzerland also there is strict justice, and we break no man's neck without trial. That expression signifies merely that your cause is lost and hopeless." Great agitation prevailed in the Knights' Hall. The roughness of the Swiss and the obstinacy of the Saxon had come into collision. The Landgrave, fearing to behold the failure of his project of conciliation, nodded assent to Zwingle's explanation. "Doctor," said he to Luther, "you should not be offended at such common expressions." It was in vain: the agitated sea could not again be calmed. The prince therefore arose, and they all repaired to the banqueting hall. After dinner they resumed their tasks. "I believe," said Luther, "that Christ's body is in heaven, but I also believe that it is in the sacrament. It concerns me little whether that be against nature, provided that it is not against faith.[240] Christ is substantially in the sacrament, such as he was born of the Virgin." [240] Non curo quod sit contra naturam, modo non contra fidem.--(Zw. Opp. iv. p. 178.)
