4. But further, this empire dares to offer up the dearest affections of the natural man to the more uninterrupted service of God. It requires of all those whom it employs in the office of teaching a surrender of the liberty to engage in those ties which the Gospel itself seeks, not to proscribe, but to sanctify. Thus the Communion, which honours marriage as a sacrament, requires of all members of its hierarchy, down to the subdeacon inclusively, to abstain from it. It regards them as the militia of the Church; and "no man that warreth entangleth himself with the affairs of this life." Multitudes there are besides, both of men and women, who accept not only this condition, but voluntarily embrace the vows of poverty and obedience in addition. To all these this spiritual empire promises one only compensation, great indeed, but received by faith alone; that, in proportion as they surrender all delight arising from the creature, and bring their will into subjection to another, the larger shall be their inheritance in the Creator; the more absolute the union of their will with His. And on this super-human life, founded in self-renunciation, and supported by Divine love, all great works in the Roman Communion depend. Not only is it the condition of the whole hierarchy, of all who have the Church's commission publicly to teach her belief, but the task of education, from the highest to the lowest classes, and the manifold labours of charity for the sick and poor, are all committed to those who give this proof of the sincerity of their vocation. 5. Lastly, in this spiritual empire there are a great number of institutions or congregations of men specially intended for its wider extension among yet heathen nations. To the conditions above enumerated they must add a yet more special aptitude for the most difficult and laborious work; a yet more complete surrender of human praise, reward, comfort, or support. Sisters of charity are seen to cross over the ocean to the extremity of the world, that they may work in combination with missionaries, whose task it is to live among savages, and to make them first men, in order that they may hereafter be Christians; both alike without endowment, in simple dependence on Providence, trusting to the labour of their hands for maintenance, putting their lives in the power of the faithless and fickle savage, and showing him, by their own homelessness, that they but live and labour for him. Nor has the blood of martyrs wholly ceased to flow. Seventy persons in China, Tonking, and Cochin China, have in the last fifty years borne witness with their lives to the faith of Christ--some of them Frenchmen and Spaniards, but some likewise priests and catechists taken out of one of the naturally feeblest races of the East, whom the grace of God nerved to endure torments unsurpassed for their severity in the earliest persecutions of the Church.
