Every member of the armed forces is morally obliged to resist orders that call for perpetrating crimes against the law of nations and the universal principles of this law. Cf. Catechism of the Catholic Church, 2313. Military personnel remain fully responsible for the acts they commit in violation of the rights of individuals and peoples, or of the norms of international humanitarian law. Such acts cannot be justified by claiming obedience to the orders of superiors. Conscientious objectors who, out of principle, refuse military service in those cases where it is obligatory because their conscience rejects any kind of recourse to the use of force or because they are opposed to the participation in a particular conflict, must be open to accepting alternative forms of service. “It seems just that laws should make humane provision for the case of conscientious objectors who refuse to carry arms, provided they accept some other form of community service”.
