People in the postmodern era have lost confidence in the idea of perpetual progress advanced by the sciences and technology. They have become distrustful of and disenchanted with authority, which includes that of the church. They value experience over against outside authority, a faith based on experience over against one that is ecclesiastically pre-formulated, and a plurality of voices that are of equal value over against a singular voice that makes all final decisions. Authenticity, being true to one’s self, is more important than giving assent; personal narrative in the context of community is more important than subscribing to creedal statements. Traditional formulations of the Christian faith and the “correct” answers to faith questions, as in catechesis, have come to be ranked as having lesser importance than one’s own personal creed and a first-hand knowledge of the Christian faith. The experience of worship, the celebration of the sacraments, spiritual practices, prayer, meditation, and the use of the arts all contribute to allowing for an encounter with the divine. As a result, people of the postmodern era have rediscovered the writings of the mystics and their way of praying and speaking with God, their attitudes toward the divine, their fundamental awareness of God’s activity and their response to it.
