Gustavus was determined, however, that the matter should not drop. Convinced that any discord inside the Church would be a benefit to the crown, he resolved to hold a theological disputation, and selected a champion from the two chief factions, with orders to appear at Christmas in Upsala and defend the doctrines of his party in open court. The Lutheran gladiator of course was Petri, his opponent being one Peder Galle, a learned canon of Upsala. The main points that were discussed are these: man's justification; free will; forgiveness of sins; invocation and worship of saints; purgatory; celebration of vigils and masses for the dead; chanting of the service; good works, and rewards; papal and monastic indulgences; sacraments; predestination; excommunication; pilgrimages. The battle on these questions was fought, December 27, in the Chapter-house at Upsala; and the chronicle tells us, somewhat unnecessarily, that the fight was hot. Each party was struggling for the very kernel of his faith. If the Bible were acknowledged to be our sole authority in religious things, the whole fabric of the papal Church was wrong. On the other hand, if power were granted to the Fathers to establish doctrines and methods supplementary to the Bible, the Lutherans had no right to disobey. As Gustavus was arbiter of the battle, there could be no doubt of the result. Petri is asserted to have come off victor, on the ground that his citations were all from Holy Writ.[107] Flattered by this great victory, the Lutherans grew bold. Though not so turbulent as before the riot, they showed much indiscretion, and Gustavus often found it necessary to interfere. What annoyed him chiefly was their bravado in alluding to the popes and bishops. The hierarchy of Romanism was fixed so firmly in people's hearts that every effort to dislodge it caused a jar. Especially in the rural districts was it necessary not to give alarm. A single deed or word might work an injury which many months of argument could not efface. It is not strange, therefore, that the king was troubled when Petri, in February, 1525, violated every rule of Church propriety by being married publicly in Stockholm. The marriage fell like a thunderclap upon the Church. Brask apparently could not believe his ears. He dashed off a letter to another prelate to inquire whether the report was true, and finding that it was, wrote to the archbishop as well as to the king, denouncing the whole affair. "Though the ceremony has been performed," he argued, "the marriage is invalid, for such was the decree made by the sixth Council of the Church." In his letter to the king, Brask used these words: "Your Majesty must be aware that much talk has been occasioned by the marriage in your capital of Olaus Petri, a Christian priest. At a future day, should the marriage result in children, there will be much trouble, for the law declares that children of a priest shall stand, in matters of inheritance, on a par with bastards....
