[Footnote 30: _1 Maccabees_, xiii. 3. Thomas Aquinas (_Summa theologica_, ii-ii. 188. 3) quotes this passage in support of the doctrine, that fighting may be directed to the preservation of divine worship.] [Footnote 31: _Deuteronomy_, xiii. 15 _sq._] [Footnote 32: _Cf._ Constant, _De la religion_, ii. 229 _sq._] It was thus in perfect consistency with the general teachings of the Church that she regarded an exploit achieved against the infidels as a merit which might obliterate the guilt of the most atrocious crimes. Such a {351} deed was the instrument of pardon to Henry II. for the murder of Becket,[33] and was supposed to be the means of cure to St. Louis in a dangerous illness. Fighting against infidels took rank with fastings, penitential discipline, visits to shrines, and almsgivings, as meriting the divine mercy.[34] He who fell in the battle could be confident that his soul was admitted directly into the joys of Paradise.[35] And this held good not only of wars against Muhammedans. The massacres of Jews and heretics seemed no less meritorious than the slaughter of the more remote enemies of the Gospel. Nay, even a slight shade of difference from the liturgy of Rome became at last a legitimate cause of war. [Footnote 33: Lyttelton, _History of the Life of King Henry the Second_, iii. 96.] [Footnote 34: _Cf._ Milman, _History of Latin Christianity_, iv. 209.] [Footnote 35: _Cf._ Laurent, _Études sur l'histoire de l'humanité_, vii. 257.] It is true that these views were not shared by all. At the Council of Lyons, in 1274, the opinion was pronounced, and of course eagerly attacked, that it was contrary to the examples of Christ and the Apostles to uphold religion with the sword and to shed the blood of unbelievers.[36] In the following century, Bonet maintained that, according to Scriptures, a Saracen or any other disbeliever could not be compelled by force to accept the Christian faith.[37] Franciscus a Victoria declared that "diversity of religion is not a cause of just war";[38] and a similar opinion was expressed by Soto,[39] Covarruvias a Leyva,[40] and Suarez.[41] According to Balthazar Ayala, the most illustrious Spanish lawyer of the sixteenth century, it does not belong to the Church to punish infidels who {352} have never received the Christian faith, whereas those who, having once received it, afterwards endeavour to prevent the propagation of the Gospel, may, like other heretics, be justly persecuted with the sword.[42] But the majority of jurisconsults, as well as of canonists, were in favour of the orthodox view that unbelief is a legitimate reason for going to war.[43] And this principle was, professedly, acted upon to an extent which made the history of Christianity for many centuries a perpetual crusade, and transformed the Christian Church into a military power even more formidable than Rome under Cæsar and Augustus. Very often religious zeal was a mere pretext for wars which in reality were
