ˈtrɪnɪti
The Christian doctrine of one God existing in three persons: Father, Son, and Holy Spirit.
Which of us comprehendeth the Almighty Trinity? and yet which speaks not of It, if indeed it be It? Rare is the soul, which while it speaks of It, knows what it speaks of. And they contend and strive, yet, without peace, no man sees that vision.
Augustine, Confessions
