Here is raised the great question,--Did Bruno adopt Calvinism? Before the Inquisition fifteen years later he practically denied this, yet acknowledged attending the lectures of Balbani, of Lucca, as well as of others who taught and preached in Geneva. Under the regulations of the Academy (University), where he had already registered, certain regulations must be complied with, and Bruno appears to have obeyed them in at least a certain degree. But the immediate cause for his departure from Geneva appears to have been one of his outbreaks of cynicism and accurate scholarship, since in 1579 he was called before the Council for having caused to be printed a document enumerating twenty errors made by the Professor of Philosophy (de la Faye) in one of his lectures. The latter was incensed and outraged at this criticism and disparagement of his views and learning, and the quarrel assumed unexpected magnitude, since Bruno, on his second appearance before the Consistory or supreme tribunal of the Church, denied the charges and called the ministers "pedagogues." These gentlemen decided to refuse him communion unless he should confess and repent of his faults and make due apology. His acceptance of these conditions not being hearty enough to suit his judges, he was admonished and excluded from the communion. These steps lead to greater contrition on his part, and the ban of excommunication was withdrawn. This sentence of exclusion was the only one within the power of the Consistory to pass, but does not prove that Bruno had accepted the protestant faith, nor partaken of its communion. In fact at his trial he steadfastly denied this. It seemed however, to disgust him with Calvinism, against which thereafter he never ceased to inveigh. Later he contrasted it with Lutheranism which was far more tolerant, and still later gave him a heartier welcome. Calvin, it must be remembered, had written a polemic against Servetus, "in which it is shown to be lawful to coerce heretics by the sword." As between the council of Trent and Calvin it certainly must have been hard, in those days, to select either a faith, or an abiding place where that faith might be peaceably practised. Doubtless Bruno's views concerning the philosophy of Aristotle conflicted with those of the church authorities, for Beza (Calvin's follower), had stated that they did not propose to swerve one particle from the opinions of that Greek philosopher, to whom, though of pagan origin, the Church, both Roman and Protestant, was for centuries so firmly bound.
