ETA, You are correct. The mind of the saints have considered the immense depths of such truths. Even St. Basil much earlier in Church history pondered the inseparability of the Divine persons in Letter XXXVIII.4 which was addressed to a Brother Gregory: ...And by the same considerations, whereby a reflective student could perceive the greatness of any one of the (Persons) believed in in the Holy Trinity, he will proceed without variation. Beholding the glory in Father, Son, and Holy Ghost, his mind all the while recognizes no void interval wherein it may travel between Father, Son, and Holy Ghost, for there is nothing inserted between Them; nor beyond the divine nature is there anything so subsisting as to be able to divide that nature from itself by the interposition of any foreign matter. Neither is there any vacuum of interval, void of subsistence, which can make a break in the mutual harmony of the divine essence, and solve the continuity by the interjection of emptiness. He who perceives the Father, and perceives Him by Himself, has at the same time mental perception of the Son; and he who receives the Son does not divide Him from the Spirit, but, in consecution so far as order is concerned, in conjunction so far as nature is concerned, expresses the faith commingled in himself in the three together. He who makes mention of the Spirit alone, embraces also in this confession Him of whom He is the Spirit. And since the Spirit is Christ’s and of God,2038 as says Paul, then just as he who lays hold on one end of the chain pulls the other to him, so he who “draws the Spirit,”2039 as says the prophet, by His means draws to him at the same time both the Son and the Father. And if any one verily receives the Son, he will hold Him on both sides, the Son drawing towards him on the one His own Father, and on the other His own Spirit. For He who eternally exists in the Father can never be cut off from the Father, nor can He who worketh all things by the Spirit ever be disjoined from His own Spirit. Likewise moreover he who receives the Father virtually receives at the same time both the Son and the Spirit; for it is in no wise possible to entertain the idea of severance or division, in such a way as that the Son should be thought of apart from the Father, or the Spirit be disjoined from the Son. But the communion and the distinction apprehended in Them are, in a certain sense, ineffable and inconceivable, the continuity of nature being never rent asunder by the distinction of the hypostases, nor the notes of proper distinction confounded in the community of essence. But I think we have to be gentle with Sunburst in this regard: when Jesus walked the earth, his communion with the Father and the Spirit was never broken, even by his physical death on the Cross. Yet, His disciples saw only the Son. So according to our senses, when we gaze upon the Sacred Host at its elevation at the Consecration, we only see the transubstantiated Presence of the Son in the Host! Doesn't this awesome moment teach us of the humility of the Father and Holy Spirit, who are fully present, yet "choose" to await our experience of the Beatific Vision to engulf us in the fullness of experiential Love! Romans 11:33 O the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways! 34 "For who has known the mind of the Lord, or who has been his counselor?" 35 "Or who has given a gift to him that he might be repaid?" 36 For from him and through him and to him are all things. To him be glory for ever. Amen. O how I love God!
