To suffer with the other and for others; to suffer for the sake of truth and justice; to suffer out of love and in order to become a person who truly… - Benedict XVI

Men in a totally planned world will find themselves unspeakably lonely. If they have completely lost sight of God, they will feel the whole horror of their poverty. Then they will discover the little flock of believers as something wholly new. They will discover it as a hope that is meant for them, an answer for which they have always been searching in secret.

And above all, what a strange attitude that actually is, when we no longer find Christian service worthwhile if the denarius of salvation may be obtained even without it! It seems as if we want to be rewarded, not just with our own salvation, but most especially with other people's damnation - just like the workers hired in the first hour. That is very human, but the Lord's parable is particularly meant to make us quite aware of how profoundly un-Christian it is at the same time. Anyone who looks on the loss of salvation for others as the condition, as it were, on which he serves Christ will in the end only be able to turn away grumbling, because THAT kind of reward is contrary to the loving-kindness of God.
