“The Holy Church sails along the waves of the sea of life for the entirety of its existence — for the centuries, millennia that it will endure. While it belongs to the world by virtue of its existence in the world, it does not belong to it in spirit; as the Lord said to the Church through its Apostles: ‘You are not of the world, but I chose you out of the world [John 15:19]. According to your bodies and needs, you belong to the world. But according to your spirit, you are foreign to the world; because you belong to God, Whom the world has despised’ [cf. John 15:18-19].”
