By his character and natural gifts, Leo the Thirteenth is essentially active rather than contemplative, and it is not surprising that the chief acts of his pontificate should have dealt rather with political matters than with questions of dogma and ecclesiastical authority. It has certainly been the object of the present Pope to impress upon the world the necessity of Christianity in general, and of the Roman Catholic Church in particular, as a means of social redemption and a factor in political stability. This seems to be his inmost conviction, as shown in all his actions and encyclical letters. One is impressed, at every turn, by the strength of his belief in religion and in his own mission to spread it abroad. In regard to forms of faith, the opinions of mankind differ very widely, but the majority of intelligent men now living seem to hold a more or less distinct faith of one sort or another, and to require faith of some sort in their fellow-men. Common atheism has had its little day, and is out of fashion. It is certainly not possible to define that which has taken the place of the pseudo-scientific materialism which plagued society twenty or thirty years ago, and it is certainly beyond the province of this book to examine into the current convictions with which we are to begin the twentieth century. Unprejudiced persons will not, however, withhold their admiration in reviewing the life of a man who has devoted his energies, his intelligence and his strength, not to mention the enormous power wielded by him as the head of the Church, to the furtherance and accomplishment of ends which so many of us believe to be good. For the pontificate of Leo the Thirteenth has differed from that of his predecessor in that it has been active rather than passive. While Pius the Ninth was the head of the Church suffering, Leo the Thirteenth is the leader of the Church militant. This seems to be the reason why he has more than once been accused of inconsistency in his actions, notably in his instructions to French Catholics, as compared with the position he has maintained towards the Italian government. People seem to forget that, whereas the question of temporal power is deeply involved in the latter case, it has nothing whatever to do with the former, and as this question is the one most often brought up against the papacy and discussed in connection with it by people who seem to have very little idea of its real meaning, it may be as well to state here at once the Pope's own view of it.
