Words David Bentley Hart Uses (with reckless abandon)

monad
3. Philosophy.
a. (in the metaphysics of Leibniz) an unextended, indivisible, and indestructible entity that is the basic or ultimate constituent of the universe and a microcosm of it.
b. (in the philosophy of Giordano Bruno) a basic and irreducible metaphysical unit that is spatially and psychically individuated.

plenitude

Sobornost
3. Russian, Religion. Kireevsky asserted that "the sum total of all Christians of all ages, past and present, comprise one indivisible, eternal living assembly of the faithful, held together just as much by the unity of consciousness as through the communion of prayer". The term in general means the unity that is the church, based on individual like minded interest.

dégringolade
French. a quick deterioration or breakdown, as of a situation or circumstance.

i assume i'll have to look up a dictionary for the untranslated greek and latin (latin includes vinculum caritatis and causa in fieri)

i do thank God for dictionary.com (where all these references are sourced)

we're now up to page 187 of Hart's the Beauty of the Infinite, through but a fraction of his breathtaking, brain-exploding section on the trinity.

He summarises point 2. as

"The Christian understanding of difference and distance is shaped by the doctrine of the Trinity, where theology finds that the true form of difference is peace, of distance beauty" (p187)

i most enjoyed this section, where difference is shown to be peace and not threat, and distance is indeed beautiful. a hard read, but well worth it.
