One of the last things we did at the seminar with Bernard McGinn this past weekend was read through and discuss Saint Francis of Assisi's poem and religious song Canticle of the Sun. McGinn considers this to be a very mystical text from Francis, as Francis seems to see God powerfully in and throughout the whole of creation, including in the sun, moon, stars, Earth, etc. McGinn noted that it is a kind of nature mysticism. Francis wrote most of it in the year 1224, and the last few lines in 1226 just before his death.
This weekend I had the fortunate opportunity to go to Fairfax, Virginia, to attend a seminar hosted by the Shalem Institute, an organization that fosters contemplative living and leadership. Their invited guest to present for their annual Gerald May Seminar was Bernard McGinn, who is Professor Emeritus of Historical Theology and of the History of Christianity in the Divinity School at the University of Chicago. McGinn is an American Roman Catholic Theologian and is considered one of the world's foremost expert scholars on the history of Christian mysticism. He has written seven volumes outlining the history of Christian mysticism, and may write two more, bringing the history up to the present time. This series is known as The Presence of God.
