nature of these acts naturally turned to them as the exhibitions of perfect goodness, all systems of ethics founded upon innate moral perceptions would be false. But happily this is not so. Those who embrace these doctrines do so only because they believe that some inspired Church or writer has taught them, and because they are still in that stage in which men consider it more irreligious to question the infallibility of an apostle than to disfigure by any conceivable imputation the character of the Deity. They accordingly esteem it a matter of duty, and a commendable exercise of humility, to stifle the moral feelings of their nature, and they at last succeed in persuading themselves that their Divinity would be extremely offended if they hesitated to ascribe to him the attributes of a fiend. But their moral feelings, though not unimpaired by such conceptions, are not on ordinary subjects generically different from those of their neighbours. With an amiable inconsistency they can even find something to revolt them in the lives of a Caligula or a Nero. Their theological estimate of justice and mercy is isolated. Their doctrine is accepted as a kind of moral miracle, and as is customary with a certain school of theologians, when they enunciate a proposition which is palpably self-contradictory they call it a mystery and an occasion for faith. In this instance a distinct moral contradiction is consciously admitted. In the case of persecution, a strictly moral and logical inference is drawn from a very immoral proposition which is accepted as part of a system of dogmatic theology. The two elements that should be considered in punishing a criminal are the heinousness of his guilt and the injury he inflicts. When the greatest guilt and the greatest injury are combined, the greatest punishment naturally follows. No one would argue against the existence of a moral faculty, on the ground that men put murderers to death. When therefore theologians believed that a man was intensely guilty who held certain opinions, and that he was causing the damnation of his fellows if he propagated them, there was no moral difficulty in concluding that the heretic should be put to death. Selfish considerations may have directed persecution against heresy rather than against vice, but the Catholic doctrines of the guilt of error, and of the infallibility of the Church, were amply sufficient to justify it.
