Dear Slawomir
You asked

> adunamentum
*ad- (from Latin, "to (become)") a sense of motion or direction, or
change
*una (from Latin = unum/una = one, oneness) oneness
*-mentum (from Latin = mentum = process of) forming, result of or by
means of an action.
*adunamentum - (from Latin = a process of becomeing one with)
This word is the origin of the English word "atonement" -
meaning "expiation, reparation for wrong or injury, reconciliation of
God and man, expiation of human sins by Christ permitting atonement
of humanity with God in heaven."
Hope this helps
