walked round their cloisters were too often assailed by pictures which could only awaken thoughts unsanctified. If the first of these two discords is eloquent of the faith which set the worship of God far before the common needs of men, the second is indicative of that alien spirit, untamed and powerful, which fights against the higher nature and the devoted life. From rebellious nature sprang all manner of unholy lusts and ambitions, productive of wars and enmities and other kinds of evil, which rendered the reality of human existence so divergent from the Christian ideal. But Christianity accepted these inevitable consequences of original sin, providing through repentance and penance reconciliation and the possibility of amendment. In the elemental passions, however, the Church found itself faced by a problem which presents one of the most interesting features of the ecclesiastical history of the Middle Ages. It is ever a hard task to expel nature, and often, where she has been renounced and thwarted, she has her revenge by returning, clothed in her grossest forms. The literature of the Thebaid and of mediæval hagiology is eloquent testimony to the fact that extreme asceticism and extreme profligacy are often found in close proximity. The fugitive from the insurgent passions of his own being, seeking to overcome the temptations of the flesh by severe macerations and scourgings, has only too often found his voluntary existence of self-discipline intolerable without the relief of an occasional wild debauch or has found that in his savage attempt to subdue the senses he has come to take a sensual delight in self-torture and that he is falling into the lowest depths of bestiality. The very fervour of religious zeal in the Middle Ages is a token of the fierceness of the passionate fires that tortured men’s hearts. It was always doubtful what outlet these fires would find. Would they glorify God in the martyrdom of the lower nature or would they rage untamed, flames solely of desire, destroying the soul? Was it a pure religious passion or a depraved sensual passion that, when the Albigensian Crusade was being preached in Germany, drove women who could not take the cross to run naked through the streets in ecstasy? Which was it that was really evidenced by the practices of the Flagellants, who at one time obtained considerable influence in different parts of Europe? They were simply doing in public what the monk did in seclusion and in the perfect odour of sanctity. The idea of bringing the soul nearer to God by the wounding of the sinful flesh had the Church’s fullest sanction. Yet the Flagellants were eventually declared heretics. Why? Because it became plain after a time that the motive of some of those who joined the sect was unholy—not a desire to seek salvation, but only a perverted lust. Secondly, because alike the genuine and the false devotee were moved in the excess of their strange
