St. Hildegard of Bingen lived during the Middle Ages and is considered by many to be one of the finest visionaries of that period.
I love the imagery in her words:
"Listen: there was once a king sitting on his throne. Around Him stood great and wonderfully beautiful columns ornamented with ivory, bearing the banners of the king with great honor. Then it pleased the king to raise a small feather from the ground, and he commanded it to fly. The feather flew, not because of anything in itself but because the air bore it along. Thus am I, a feather on the breath of God."
Interestingly, Hildegard is suspected of having suffered terrible migraines during her life. The famed neurologist Dr. Oliver Sacks proposed that at least some of her visions may have been a result of her pain.
Here is a prayer (in contemporary language) to guide our Sunday path...
O God, by whose grace your servant Hildegard, kindled with the Fire of your love, became a burning and shining light in your Church: Grant that we also may be aflame with the spirit of love and discipline, and walk before you as children of light; through Jesus Christ our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
