While 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. There may be a legitimate diversity of opinion even among Catholics about waging war and applying the death penalty, but not however with regard to abortion and euthanasia.
Pope Benedict XVIMaterial possessions, in themselves, are good. We would not survive for long without money, clothing and shelter. We must eat in order to stay alive. Yet if we are greedy, if we refuse to share what we have with the hungry and the poor, then we make our possessions into a false god. How many voices in our materialist society tell us that happiness is to be found by acquiring as many possessions and luxuries as we can! But this is to make possessions into a false god. Instead of bringing life, they bring death.
Pope Benedict XVIThe "door of faith" (Acts 14:27) is always open for us, ushering us into the life of communion with God and offering entry into his Church. It is possible to cross that threshold when the word of God is proclaimed and the heart allows itself to be shaped by transforming grace. To enter through that door is to set out on a journey that lasts a lifetime.
Pope Benedict XVIHow much filth there is in the church, even among those who, in the priesthood, should belong entirely to Him. How much pride, how much self-sufficiency.
