The Indwelling of the Holy Spirit in Souls¹

[From the same Encyclical, "Mystici Corporis," June 29, 1943]

2290. Surely we are not ignorant of the many veils that stand in the way of our understanding and explaining this profound doctrine, which is concerned with our union with the divine Redeemer, and with the indwelling of the Holy Spirit in a special way in souls; veils by which this profound doctrine is enveloped as by a kind of cloud, because of the weakness of the minds of those who make inquiry. And we know also that from correct and persistent investigation of this subject, and from the conflict of various opinions and the clash of ideas, provided love of truth and due obedience to the Church direct such investigations, precious light abounds and comes forth, by which also in the sacred science akin to this actual progress is attained. Therefore, we do not censure those who enter upon diverse ways and methods of reasoning to understand, and according to their power to clarify the mystery of this marvelous union of ours with Christ. But let this be a general and unshaken truth, if they do not wish to wander from sound doctrine and the correct teaching of the Church: namely, that every kind of mystic union, by which the faithful in Christ in any way pass beyond the order of created things and wrongly enter among the divine, so that even a single attribute of the eternal Godhead can be predicated of these as their own, is to be entirely rejected. And, besides, let them hold this with a firm mind as most certain, that all activities in these matters are to be held as common to the Most Holy Trinity, insofar as they depend upon God as the supreme efficient cause.

Let them note also that there necessarily is here a question of a hidden mystery, which in this earthly exile, being covered by a veil, can never be looked into or be described by human tongue. Indeed, the divine Persons are said to indwell inasmuch as being present in an inscrutable manner in animate creatures endowed with intellect they are attained by them through knowledge and love,² yet in a manner intimate and unique that transcends all nature. Indeed, to contemplate this so as at least to approach it slightly, that way and method are not to be over-looked which the Vatican Synod [sess. 3, Const. de fid. cath., cap. 4; see n. 1795] strongly recommended in matters of this kind; this method,
