“The Church is the Church only when it exists for others...not dominating, but helping and serving. It must tell men of every calling what it means to live for Christ, to exist for others.”

“Let the Christian remain in the world, not because of the good gifts of creation, nor because of his responsibility for the course of the world, but for the sake of the Church. Let him remain in the world to engage in frontal assault on it, and let him live the life of his secular calling in order to show himself as a stranger in the world all the more. But that is only possible if we are visible members of the Church. The antithesis between the world and the Church must be borne out in the world. That was the purpose of the incarnation. That is why Christ died among his enemies. That is the reason and the only reason why the slave must remain a slave and the Christian remain subject to the powers that be.”

“No one can become a new man except by entering the Church, and becoming a member of the body of Christ. It is impossible to become a new man as a solitary individual. The new man means more than the individual believer after he has been justified and sanctified. It means the Church, the Body of Christ, in fact it means Christ himself.”

“Just as the separation of Church and world became visible only in their continuous conflict, so also does personal sanctification consist in the conflict of the Spirit against the flesh. The saints are only conscious of the strife and distress, the weakness and sin in their lives; and the further they advance in holiness, the more they feel they are fighting a losing battle and dying in the flesh. "They that are of Christ Jesus have crucified the flesh with the passions and lusts thereof" (Gal. 5.24). They still live in the flesh, but for that very reason their whole life must be an act of faith in the Son of God, who has begun his life in them (Gal. 2.20). The Christian dies daily (I Cor. 15.31), but although this may mean suffering and decay in the flesh, the inward man is renewed day by day (II Cor. 4.16). The only reason why the saints have to die in the flesh is that Christ through the Holy Spirit has begun to live his life in them. The effect of Christ and his life on the saints is that they die after the flesh. There is no need for them to go out of their way to look for suffering: indeed that would only mean a return to the self-assertion of the flesh. Every day Christ is their death and Christ is their life.”

“The community of the saints is not an "ideal" community consisting of perfect and sinless men and women, where there is no need of further repentance. No, it is a community which proves that it is worthy of the gospel of forgiveness by constantly and sincerely proclaiming God's forgiveness...Sanctification means driving out the world from the Church as well as separating the Church from the world. But the purpose of such discipline is not to establish a community of the perfect, but a community consisting of men who really live under the forgiving mercy of God.”

“The earthly form of Christ is the form that died on the cross. The image of God is the image of Christ crucified. It is to this image that the life of the disciples must be conformed; in other words, they must be conformed to his death (Phil 3.10, Rom 6.4) The Christian life is a life of crucifixion (Gal 2.19) In baptism the form of Christ's death is impressed upon his own. They are dead to the flesh and to sin, they are dead to the world, and the world is dead to them (Gal 6.14). Anybody living in the strength of Christ's baptism lives in the strength of Christ's death.”

“For the rest of mankind to be with Christ means death, but for Christians it is a means of grace. Baptism is their assurance that they are "dead with Christ", "crucified with him", "buried with him", "planted together in the likeness of his death". All this creates in them the assurance that they will also live with him. "We with Christ"--for Christ is Emmanuel, "God with us." Only when we know Christ in this way is our being with him the source of grace.”
