In consequence of his dubious attitude, Melanchthon also, who before this had been generally honored as the leader of the Lutheran Church, completely lost his prestige, even among many of his formerly most devoted friends. The grief and distress experienced by loyal Lutherans at his wavering and yielding is eloquently expressed by Antonius Corvinus, Superintendent at Kalenberg-Goettingen, the Lutheran martyr, who, because of his opposition to the Interim, was incarcerated for three years, in consequence of which he died, 1553. In a letter dated September 25, 1549, he implored his friend to abandon the Interim, and to "return to his pristine candor, his pristine sincerity, and his pristine constancy," and "to think, say, write, and do what is becoming to Philip, the Christian teacher, not the court philosopher." Peace, indeed, was desirable, but it must not be obtained by distracting the churches. Christ had also declared that He did not come to bring peace, but the sword. Even the heathen Horatius Flaccus had said: "_Si fractus illabitur orbis, impavidum ferient ruinae._" How much more should Christians avoid cowardice! One must not court the cross wantonly, but it must be borne courageously when for the sake of truth it cannot be avoided, etc. In the original, Corvinus's letter reads, in part, as follows: "O mi Philippe, o, inquam, Philippe noster, rede per immortalem Christum ad pristinum candorem, ad pristinam sinceritatem ad pristinam constantiam! Ne languescito ista tua formidine ac pusillanimitate nostrorum animos tantopere!... Non sis tantorum in ecclesia offendiculorum autor! Ne sinas, tua tam egregia scripta, dicta, facta, quibus mirifice hactenus de ecclesia ac scholis meritus es, isto condonationis, novationis, moderationis naevo ad eum modum deformari! Cogita, quantum animi ista vestra consilia et adversariis addant et nostris adimant!... Rogamus, ut, professionis tuae memor, talem te cum Vitebergensibus tuis iam geras, qualem te ab initio huius causae gessisti, hoc est, ut ea sentias, dicas, scribas, agas, quae Philippum, doctorem Christianum, non aulicum philosophum decent." (Tschackert, 506.)
