Centering Prayer was developed as a response to the Vatican II invitation to revive the contemplative teachings of early Christianity and present them in updated formats. In this way, the method of Centering Prayer is drawn from the ancient practices of the Christian contemplative heritage, notably the traditional monastic practice of Lectio Divina and the practices described in the anonymous fourteenth century classic The Cloud of Unknowing and in the writings of Christian mystics such as John Cassian, Francis de Sales, Teresa of Avila, John of the Cross, Therese of Lisieux, and Thomas Merton. Most importantly, Centering Prayer is based on the wisdom saying of Jesus in the Sermon on the Mount:
In the 1970s, answering the call of Vatican II, three Trappist monks at St. Joseph's Abbey in Spencer, Massachusetts, Fathers William Meninger, Basil Pennington and Thomas Keating, looked to these ancient sources to develop a simple method of silent prayer for contemporary people. The prayer came to be known as Centering Prayer in reference to Thomas Merton's description of contemplative prayer as prayer that is "centered entirely on the presence of God." The monks offered Centering Prayer workshops and retreats to both clergy members and laypeople. Interest in the prayer spread, and shortly after the first intensive Centering Prayer retreat in 1983, the organization Contemplative Outreach was formed to support the growing network of Centering Prayer practitioners.
Today Centering Prayer is practiced by people all around the world, creating local and global networks of Christians in communion with Christ and each other and contributing to the renewal of the contemplative dimension of Christianity.
