The Source is Christ Himself
Over the centuries, the church conserves this precious treasure, which is sacred Scripture, doctrine, the sacraments, the Ministry of pastors, so that we can be faithful to Christ and share in his very life. It is like a river coursing through history, developing, irrigating; but running water always comes from a source, and the source is Christ himself: he is the risen one, he is the living one, and his words never pass away, for he does not pass: he is alive, he is among us today, he hears us and we speak to him, and he listens; he is in our hearts.
– Pope Francis
