"The Christians of the rising Church did not regard their missionary announcement as propaganda, which had to help expand their group, but as an intrinsic need that came from the nature of their faith: the God in which they believed was everyone’s God, the one true God, who had shown Himself in the history of Israel and finally in His Son, thus giving the answer that concerned everyone and that in their hearts all men await". This is the part of the Pope’s speech about the universality of the Christian announcement, closely related to the universality of the reason that exists in the human soul. "The universality of God and the universality of the reason opened up to Him explained Benedict XVI were for them the reason and at the same time the duty of the announcement. For them, faith did not belong to the cultural tradition which differs with each people, but to the sphere of the truth that concerns everyone in the same way". In other words, for Christianity, "there must be the announcement that is directed to man, thus creating in him a belief that can turn into life". The "classical" expression of this "need of the Christian faith of making itself communicable to the others" lies in Peter’s letter: "Be always ready to answer to anyone who asks you to account for (logos) the hope that is in you".
