The Creed says that God became incarnate in one man Jesus, but the gift of the Holy Spirit is meant to establish a 'parallel dynamic' in the heart and mind of each person. 4 Culture results. The human heart and mind connects with the panoply of experience and culture - with the sciences and the humanities, with artistic, agricultural and economic life. God's gift of himself is not just if always or ever confined to exotic and esoteric experiences or with removal from the city of man into a 'purely mystical' religious realm of some separate kind. The gift of Pentecost should make a special human culture possible in which the better and the best for humanity becomes possible and attainable.
Christians can be optimistic about a human future and the possibilities of culture.
At least, some cultures will be empirically better than others in embodying normative values of such an otherwise transcendental realm. In other words, Augustine's City of Man has a natural fulfilment and end which might be attainable with the aid of His people who are alive to their true destiny and end in eternity. A future could be grasped with optimism and generosity and planned for with all our energies and informed practical wisdom. This too is a gift of God not removed from Pentecost. Within this social and contextual view of God' gifts, there is absolute space for personal and individual exploration of the notion of God's gift to me as the gift of His Holy Spirit - the cultivation of a personal devotion to God, and the exercising of all the potentialities and gifts that I might have.
