In the New Testament our enemies are those who harbor hostility against us, not those against whom we cherish hostility. For Jesus refuses to reckon … - Dietrich Bonhoeffer

The sword wherewith they judge their brethren will fall upon their own heads. Instead of cutting themselves off from the brother as the just from the unjust, they find themselves cut off from Jesus.

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 is the deadly enemy of our Church. We are fighting to-day for costly grace. Cheap grace means grace sold on the market like cheapjacks’ wares. The sacraments, the forgiveness of sin, and the consolations of religion are thrown away at cut prices. Grace is represented as the Church’s inexhaustible treasury, from which she showers blessings with generous hands, without asking questions or fixing limits. Grace without price; grace without cost!
