This petition was at once based by Luther on the general theological principles referred to above, i.e. the statement he had addressed to the Elector, declaring that, owing to the value of the Evangel, no place must be allowed in the Electorate for the practice of any religion other than the “evangelical”: Let there be but one doctrine in every place! Luther adds, that the Canons of Altenburg had indeed alleged their conscience, but that this was not a true conscience but merely a fictitious one, otherwise they would have agreed “to allow their conscience to be formed and instructed from Scripture.” This they had refused to do, and had appealed instead to traditional usage “as vouched for by the Church,” “thereby giving ample proof that their plea concerning their conscience was an invention and only brought forward for the sake of preserving appearances; for a true conscience desires nothing so ardently as to be instructed from Scripture.” If they wished to continue publicly to blaspheme the true God by their worship, they must “prove from Scripture their right and authorisation to do so.”[938] The Canons were convinced that there was no need for them to prove to Luther their right from the Bible, and also that the best proof would be of no avail. The decision on the validity of any such proof lay in the last instance with the Electoral Court, and he would indeed have been blind who could have expected in that quarter any judgment differing from Luther’s. * * * * * Recourse was accordingly taken to force, and the Catholic religion was obliged to retire from its last foothold. Nevertheless, a large number of the burghers of Altenburg remained secretly faithful to the Church of their fathers. When, in 1528, the Lutheran visitors held an enquiry there, the town-councillors, who themselves were on the side of Luther, declared there were still “many Papists” in the town.[939] * * * * *
