Consequently, if we remember, venerable brothers and all of you, our children, gathered here, how in everyone we can and must recognize the countenance of Christ (cf. Matt. 25:40), the Son of Man, especially when tears and sorrows make it plain to see, and if we can and must recognize in Christ's countenance the countenance of our heavenly Father "He who sees me," Our Lord said, "sees also the Father" (John 14:9), our humanism becomes Christianity, our Christianity becomes centered on God; in such sort that we may say, to put it differently: a knowledge of man is a prerequisite for a knowledge of God.
Would not this council, then, which has concentrated principally on man, be destined to propose again to the world of today the ladder leading to freedom and consolation? Would it not be, in short, a simple, new and solemn teaching to love man in order to love God? To love man, we say, not as a means but as the first step toward the final and transcendent goal which is the basis and cause of every love. And so this council can be summed up in its ultimate religious meaning, which is none other than a pressing and friendly invitation to mankind of today to rediscover in fraternal love the God "to turn away from whom is to fall, to turn to whom is to rise again, to remain in whom is to be secure...to return to whom is to be born again, in whom to dwell is to live" (St. Augustine, Solil. I, 1, 3; PL 32, 870).
