Mournier defined his own position as one of 'tragic optimism--' a Christian attitude of absolute engagement in the struggles of history, despite the fact that the Absolute cannot be contained in history.
As persons, so Mournier maintained, we possess both a spiritual and temporal dimension; we exist in history, in relationship with others, but open to transcendence and ultimately to God. This concept of the person, he believed, was denied as much by an atheistic totalitarianism of the Left as by the bourgeois materialism of capitalist society. To the extent that Christianity had become infected by the bourgeois spirit, it had become a prop in what he called, 'the established disorder.
The definition of God as infinite Love was a particularly important theme for [John Duns] Scotus. He disagreed with Anselm, who understood the Incarnation as a necessary payment for sin. He also disagreed with Thomas [Aquinas], who argued that the Incarnation, though willed by God from eternity, was made necessary by the existence of sin. For Scotus the Incarnation was willed through eternity as an expression of God's love, and hence God's desire for consummated union with creation. Our redemption by the cross, though caused by sin, was likewise an expression of God's love and compassion, rather than as an appeasement of God's anger or a form of compensation for God's injured majesty. Scotus believed that...knowledge of God's love should evoke a loving response on the part of humanity. 'I am of the opinion that God wished to redeem us in this fashion principally in order to draw us to his love.' Through our own loving self-gift, he argued, we join with Christ 'in becoming co-lovers of the Holy Trinity.
