In the Bible the cross is the expression of a life that is completely being for others. It is not man who goes to God with a compensatory gift, but God who comes to man, in order to give to him. He restores disturbed right on the initiative of his own power to love, by making unjust man just again, the dead living again, through his own creative mercy.
In the New Testament the cross appears primarily as a movement from above to below. It does not stand there as the work of expiation which mankind offers to the wrathful God, but as the expression of that foolish love of God's which gives itself away to the point of humiliation in order thus to save man; it is his approach to us, not the other way about.
Pope Benedict XVI
