According To The Teaching of St. Thomas Aquinas
PART SECOND
GOD'S SPECIAL PRESENCE OR THE INDWELLING
OF THE HOLY GHOST IN THE SOULS
OF THE JUST
CHAPTER I
The Fact of God's Special Presence in the Just.
The Sending and the Bestowal of God the
Holy Ghost; His Indwelling
in the Soul
Despite their brevity, these words of St. Thomas contain a wonderful summary of the question we are studying. Here we find clear mention of, first, the! fact of this special presence of God in the soul which is in the state of grace; second, the nature of this presence; it is a substantial, that is to say, a most real presence; God is present not merely by His favors, but in: Person; third, the mode of this presence: He is there no longer in the capacity of an active or efficient cause, but as a Guest and a Friend, as an object of knowledge and love; fourth, the subjects who alone can benefit by such a gift, must be rational beings; fifth, the condition for this presence is the state of grace.
To be well understood, these considerations should each be deeply pondered; they shall receive a treatment proportioned to the difficulties each may present, and to the degree of their importance. We shall devote our attention first to the fact of this special presence of God in the souls of the just.
