The Holy Spirit is given by God alone, yet not wholly to
each person, since there is no one besides Christ capable of receiving
Him wholly. Charity is shed abroad by the Holy Spirit, Who,
prefigured by the mystical ointment, is shown to have nothing common
with creatures; and He, inasmuch as He is said to proceed from the
mouth of God, must not be classed with creatures, nor with things
divisible, seeing He is eternal.
