On February 29, 1919, Jung wrote a letter to Joan Corrie and commented on the Sermones, with particular reference to the last one:

“The primordial creator of the world, the blind creative libido, becomes transformed in man through individuation & out of this process, which is like pregnancy, arises a divine child, a reborn God, no more (longer) dispersed into the millions of creatures, but being one & this individual, and at the same time all individuals, the same in you as in me.

Dr. L[ong] has a little book: VII sermones ad mortuous. There you find the description of the Creator dispersed into his creatures, & in the last sermon you find the beginning of individuation, out of which, the divine child arises … The child is a new God, actually born in many individuals, but they don’t know it. He is a spiritual God.

A spirit in many people, yet one and the same everywhere. Keep to your time and you will experience His qualities” (Copied in Constance Long’s diary, Countway Library of Medicine, pp. 21-22) ~The Red Book, Footnote 123.
