So I looked into the quote that I mentioned on pg. 271. "Is this not precisely the doctrine of the Latins, for which they were ejected from within our Church, namely, that it is not the grace but the very Holy Spirit himself who is both sent from the Son and poured out through the Son?" This quote was left out of the Classics of Western Spirituality abridged version printed by Paulist Press. I highly suggest getting the full translation since important quotes and doctrines like these are left out.
