"If Christ's light is to shine anew upon all human beings, the commitment to seeking the visible unity of all Christians is essential…To believe in Christ means to desire unity; to desire unity means to desire the Church…We Christians must be aware of the task entrusted to us, which is to bring to Europe and to the world the voice of the One who said: 'I am the light of the world; he who follows me will not walk in darkness, but will have the light of life' (Jn 8: 12). It is up to us to make Christ's light shine on today's people."
--Pope Benedict XVI, 2007
