We consider the democratisation of the quest for silence in industrial society: the tangling of a secular society with the silences provided by Christian tradition, through for instance the popularity of retreats, or the observance of silence in remembrance. We see the importance of 'whistle-blowing' to modern Christianity, and its use of the historical discipline. We ponder the relation of agnosticism to silence; the role of music in silence and Christian understanding; the relationship between Word and Spirit in the future of Christian life.

In the fifth lecture of the Aberdeen Gifford Lecture Series 2012, Professor Sarah Coakley takes up the challenges left by the last two lectures, and now confronts the contentious and multi-levelled question about "teleology" in evolution.

So far, the story has largely been about overt history: the positive utterances and actions of public Christianity. We turn now to further and more complex varieties of silence: first the phenomenon of 'Nicodemism', simultaneously audible to those with ears to hear, and not to be heard by others.

The noisiness of Protestantism, particularly exacerbated by the end of monasticism, unsuccessfully countered in the Church of Zürich but transcended first among radical Reformers (especially Caspar Schwenckfeld and Sebastian Franck) and a century later by the Society of Friends. The difficulties of contemplatives in the Counter-Reformation, where activism was the characteristic of the new foundations of Jesuits and Ursulines, and the problems faced by such revivals as the Discalced Carmelites. The troubles of Madame Guyon and Quietists.
