I cam across this article today, about Ravens and their relationship to the saints. It is a very interesting read that I highly recommend.
In pop culture, ravens are often associated with death or dark arts/supersition or witchcraft. However many people fail to realise how often they appear in the lives of saints and especially in the Bible.
For many new age people, the raven is often seen as a symbol of the Morrigan - an ancient Irish goddess of war and magic. However, in Christian literature going back to the prophet Elijah, ravens are associated with hermits, as well as a symbol of God's Providence as the above article outlines.
The author makes a great connection between the ravens as a symbol of God's Providence, and the need for Christian's to reclaim stewardship of Creation and integration with God's creation. In this sense, it could be read as a flow on from Pope Francis' Encyclical Laudato Si.
May we all have a greater awareness of God's goodness and Providence in creation, and learn to adore him through his creation.
