Page 454, A Brief Theological Creed
The incomprehensible term of human transcendence, which takes place in man’s existentiell and original being and not only in theoretical or merely conceptual reflection, is called God, and he communicates himself in forgiving love to man both existentielly and historically as man’s own fulfilment. The eschatological climax of God’s historical self-communication, in which this self-communication becomes manifest as irreversible and victorious, is called Jesus Christ.
Page 456, A Brief Anthropological Creed
A person really discovers his true self in a genuine act of self-realization only if he risks himself radically for another. If he does this, he grasps unthematically or explicitly what we mean by God as the horizon, the guarantor and the radical depths of this love, the God who in his existentiell and historical self-communication made himself the realm within which such love is possible. This love is meant in both an interpersonal and a social sense, and in the radical unity of both of these elements it is the ground and the essence of the church.
Page 457, A Brief Future-Oriented Creed
Christianity is the religion which keeps open the question about the absolute future which wills to give itself in its own reality by self-communication, and which has established this will as eschatologically irreversible in Jesus Christ, and this future is called God.
