Earlier, I referred to the Zulu word ubuntu, musing on its familiar themes to Universalists.
Tonight, I was casting through those parts of the 1662 Anglican prayerbook in Zulu. (No, I don’t read Zulu, but I can control-F to find terms.) I found ubuntu (perhaps in conjunction with another word or words) in three places: a petition in the Litany, in the Athanasian Creed, and in the collect for the feast of the Annunciation. Referring to the English, it can only refer to one thing.
Incarnation, of Jesus Christ specifically.
