Romano Guardini's theory of oppositions (Gegensatzlehre), which helped him forge a unity within multifaceted realities such as Church and liturgy, also inspired him to achieve a unity between the secular and sacred aspects of the Christian life, as the Second Vatican Council was later to do, particularly in Gaudium et Spes. While Gaudium et Spes 36 concentrated on a Christian view of the autonomy of created realities, Guardini diagnosed the gulf between faith and life in a neglect of the interplay of creation and redemption: ‘to save redemption by the Son, [man] has been forced to abandon creation by the Father’. In a way which was prophetic of later criticisms of Gaudium et Spes and also of fruitful applications and developments of its doctrine, Guardini called for a reflection on the light which the work of redemption sheds on the created world and on man's life within it, that the believer may stand with his faith amid the concrete, actual world, and rediscover that world in his faith.
