The glory of God is the living man, but the life of man is the vision of God', says St. Irenaeus, getting to the heart of what happens when man meets God on the mountain in the wilderness. Ultimately, it is the very life of man, man himself as living righteously, that is the true worship of God, but life only becomes real life when it receives its form from looking toward God.
Pope Benedict XVIPeace, however, is not merely a gift to be received: it is also a task to be undertaken. In order to be true peacemakers, we must educate ourselves in compassion, solidarity, working together, fraternity, in being active within the community and concerned to raise awareness about national and international issues and the importance of seeking adequate mechanisms for the redistribution of wealth, the promotion of growth, cooperation for development and conflict resolution. 'Blessed are the peacemakers, for they shall be called sons of God', as Jesus says in the Sermon on the Mount
Pope Benedict XVIWhile the Church exhorts civil authorities to seek peace, not war, and to exercise discretion and mercy in imposing punishment on criminals, it may still be permissible to take up arms to repel an aggressor or to have recourse to capital punishment.
