Costly grace is the treasure hidden in the field; for the sake of it a man will gladly go and sell all he has. It is the pearl of great price to by w… - Dietrich Bonhoeffer

As Christianity spread, and the Church became more secularized, this realization of the costliness of grace gradually faded. The world was Christianized, and grace became its common property. It was to be had at low cost. Yet the Church of Rome did not altogether lose the earlier vision. It is highly significant that the Church was astute enough to find room for the monastic movement … Thus monasticism became a living protest against the secularization of Christianity and the cheapening of grace. … Monasticism was represented as an individual achievement which the mass of the laity could not be expected to emulate. By thus limiting the application of the commandments of Jesus to a restricted group of specialists, the Church evolved the fatal conception of the double standard.

Cheap grace means grace as a doctrine, a principle, a system. It means forgiveness of sins proclaimed as a general truth, the love of God taught as the Christian "conception" of God. An intellectual assent to that idea is held to be of itself sufficient to secure remission of sins. The church which holds the correct doctrine of grace has, it is supposed, ipso facto a part of that grace. In such a Church the world finds a cheap covering for its sins; no contrition is required, still less any real desire to be delivered from sin. Cheap grace therefore amounts to a denial of the living Word of God, in fact, a denial of the Incarnation of the Word of God. Cheap grace means the justification of sin without the justification of the sinner. Grace alone does everything, they say, and so everything can remain as it was before.

Jesus Christ has to suffer and be rejected. … Suffering and being rejected are not the same. Even in his suffering Jesus could have been the celebrated Christ. Indeed, the entire compassion and admiration of the world could focus on the suffering. Looked upon as something tragic, the suffering could in itself convey its own value, its own honor and dignity. But Jesus is the Christ who was rejected in his suffering. Rejection removed all dignity and honor from his suffering. It had to be dishonorable suffering. Suffering and rejection express in summary form the cross of Jesus. Death on the cross means to suffer and to die as one rejected and cast out. It was by divine necessity that Jesus had to suffer and be rejected. Any attempt to hinder what is necessary is satanic. Even, or especially, if such an attempt comes from the circle of disciples, because it intends to prevent Christ from being Christ. The fact that it is Peter, the rock of the church, who makes himself guilty doing this just after he has confessed Jesus to be the Christ and has been commissioned by Christ, shows that from its very beginning the church has taken offense at the suffering of Christ. It does not want that kind of Lord, and as Christ's church it does not want to be forced to accept the law of suffering from its Lord.
