Unquestionably in the monk’s eyes passionate love between the sexes was mainly lust. Within the bonds of marriage it was not mortal sin; but the virgin state was the best. Here, as we shall see, life was to claim its own and free its currents. Monasticism did not stop the human race, or keep men from loving women. Such love would assert itself; and ardent natures who felt its power were to find in themselves a love and passion somewhat novel, somewhat raised, somewhat enlarged. In the end the love between man and woman drew new inspiration and energy from the enhancement of all the rest of love, which came with Christianity. Evidently the great office of Christian love in a heathen period was to convert idolaters to the Faith. So it had been from the days of Paul. Rapidly Christianity spread through all parts of the Roman Empire. Then the Faith pressed beyond those crumbling boundaries into the barbarian world. Hereupon, with Gregory the Great and his successors, it became clear that the great pope is always a missionary pope, sending out such Christian embassies as Gregory sent to the Anglo-Saxon kingdoms. If conversion was a chief office of Christian love, the great object of Christian wrath was unbelief. That existed within and without Christendom: within in forms of heresy, without in the practices of heathenism. Christian wrath was moved by whatever opposed the true faith. The Christian should discriminate: hate the sin, and love the sinner unto his betterment. But it was so easy, so human, from hating the sin to hate the obdurate sinner who could not be saved and could but harm the Church. One need not recount how the disputes of the Athanasian time regarding the nature of Christ came to express themselves in curses; nor how the Christian sword began its slaughter of heretic and heathen. Persecution seemed justified in reason; it was very logical; broad reasons of Christian statecraft seemed to make for it; and often a righteous zeal wielded the weapon. It had moreover its apparent sanction in Jehovah’s destroying wrath against idolaters within and without the tribes of Israel.
