Another example may be found in the question whether a priest should serve as a combatant in his country’s army. He is called to represent the Church; and the Church is essentially, not accidentally, international; it is not international merely as a scientific society may be, in that it is not concerned with political frontiers and men of all nations are welcome within it; but it is international in the sense that it exists to bind the nations of the earth in one. The officer of such a society may be as patriotic in his feeling as anyone else, but, just because he is an official, for him to take positive action on one side of the other weakens the Church’s international position, and is, therefore, a more serious act than it is in the case of the layman. Here again there are not two standards, but there are diverse circumstances. If the Church called on all its members to refuse to serve, the result would be to interfere with the freedom of the State to act in its own sphere; if it allows everyone to serve, it is deprived of its Catholic witness just when that is most vitally needed. The only way of doing justice to the legitimate claims of both nationalism and Catholicity, is to differentiate between persons; and there is no practicable or even sensible way of doing this except to make the Church’s officers responsible for the Catholic witness and its lay, or unofficial, members for the national. But does this not involve the danger of a priestly caste? Yes, no doubt it does; but there are two ways in which we may avoid falling into that danger. The first is perpetually to remember that men are called by God to the different kinds of work which He has for them to do; and we shall avoid unctuousness, which is no doubt what men most dread about a priestly caste, if we keep it perpetually in our mind that we are not personally holy because our calling is. We are entrusted with this great charge. We have to fulfil it. It is our work for Him. But there are those whom He calls to serve Him as politicians and as soldiers; if they do their work as in His sight, and to His glory, they are serving Him every bit as much as we are. All the work of all the kinds of men is needed in the world, and it is only if we suppose that we are made more holy because our calling is concerned with the specifically holy things that we shall fall before that danger.
