Gregory says that he and Basil "felt mutual affection" that "grew daily warmer and deeper"; they shared a home, meals, goals. Taking up Gregory's homily about Basil (Gregory outlived him by about ten years), a 21st century reader who did not know their whole story might assume, at least from the first paragraphs, that this is an ancient (circa AD 380) witness to same-sex marriage. Instead it is a picture of Christian friendship: "We followed the guidance of God’s law and spurred each other on to virtue."
Wouldn't it be wonderful if more people today were to share the stories of that kind of spiritual friendship? These are stories that demonstrate the breadth of love, a warm human love that is as fulfilling as it is chaste. We can broaden the discourse about love by telling such stories!
Here are Gregory's own words, taken from today's "Office of Readings":
