Viriditas: The Greening Power of God

Hildegard’s most original idea: <em>viriditas</em>, the ‘greening power’ - the moist, fresh, life-giving force by which God quickens all creation, the sap of the Holy Spirit running through plants, bodies, and souls alike, in a theology that reads almost like an ecology.

From the lesson

Of all the words Hildegard used, none is more her own than viriditas. It comes from the Latin for green, viridis, and at its simplest it means the greenness of a growing plant. But Hildegard stretched it into something far larger: the moist, fresh, surging life-force by which God makes all things live and grow and bear fruit. Viriditas is the vitality in a bud about to open, the juice in a green stem, the fertility of a watered field - but also the health of a body, the vigor of a soul, the freshness of faith. It is greenness as a name for life itself, and behind it, for the God who is life’s source. Where a modern reader might say ‘vitality’ or ‘life-energy,’ Hildegard reached for the color of spring, because she saw in the green world the visible sign of an invisible divine power flowing through everything that is.

Hildegard most often ties viriditas to the third person of the Trinity, the Holy Spirit, the giver of life. She pictures the Spirit not only as a dove or a wind but as a kind of green fire and living moisture, a sap that rises through the whole creation as sap rises through a tree in spring. In one of her images human beings are like trees: the Holy Spirit is the greenness, the juiciness, the capacity for fruit within us, and to live in the Spirit is to stay green - supple, growing, fruitful - rather than to go dry and brittle. This is why viriditas is never merely botanical for her. The greening of a hillside in April and the greening of a soul in grace are, for Hildegard, two expressions of one divine vitality. God does not merely create the world once and stand back; God keeps it moist and living, greening it continually from within.

Because viriditas runs through everything, Hildegard’s theology is unusually attentive to the natural, bodily world - so much so that modern readers often call her a proto-ecological thinker. She did not treat creation as a mere backdrop for the human drama of sin and salvation. She saw it as charged, moment by moment, with divine life, an interconnected whole in which the health of the body, the fertility of the soil, and the vigor of the soul all draw on the same greening power. This conviction shaped her practical work as well as her mysticism: in her medical and scientific books, the Physica and Causae et Curae, she catalogued the healing powers of plants, stones, and animals precisely because she believed the same viriditas that greens a meadow could be drawn on to restore a sick body to balance. To heal was to help the greenness flow again. And there is a warning folded in: if the world is a single living web quickened by one divine vitality, then human sin can throw it out of joint - and Hildegard did speak, in strikingly modern-sounding passages, of the elements themselves falling into disorder when humanity abuses the creation entrusted to it.

This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.

What you'll be able to recall

You learned that viriditas (‘greenness’ or ‘greening power’) is Hildegard’s name for the moist, fertile life-force by which God vivifies all things, closely tied to the Holy Spirit; that its opposite is ariditas , a withering dryness; and that it links spirit, body, and the natural world in one living whole.
