Pope Benedict XVILent is like a long 'retreat' during which we can turn back into ourselves and listen to the voice of God, in order to defeat the temptations of the Evil One. It is a period of spiritual 'combat' which we must experience alongside Jesus, not with pride and presumption, but using the arms of faith: prayer, listening to the word of God and penance. In this way we will be able to celebrate Easter in truth, ready to renew the promises of our Baptism.
Pope Benedict XVIEach of you has a personal vocation which He has given you for your own joy and sanctity. When a person is conquered by the fire of His gaze, no sacrifice seems too great to follow Him and give Him the best of ourselves. This is what the saints have always done, spreading the light of the Lord ... and transforming the world into a welcoming home for everyone.
Pope Benedict XVIThe world needs more than just itself. Amid the dreariness, people do not need a distraction that will in the end become dreary itself; they are asking for mystery, even if they do not realize this themselves. They need the sign of the wholly Other, the living Word of God, entering into this our age in unadulterated trustworthiness and dynamism.
