I thought also of quoting these verses from the First Epistle of John, "Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. And everyone who has this hope in Him purifies himself, just as He is pure" 1 JN 3:2,3.
Several weeks ago I was reading a two volume work titled, "The Mystical Evolution in the Development and Vitality of the Church" by Fr. John G. Arintero, O.P.. In these volumes Fr. Arintero writes about the glorification of the saints/the spiritual espousals. I will quote from John Ruusbroec "The Spiritual Espousals"
"You shall know that the heavenly Father, as a living ground and with all that lives in him, has turned actively toward his Son as toward his own eternal wisdom, and that this same wisdom, together with all that lives in it, has actively turned back toward the Father, that is, toward the same ground from which it comes forth. In this meeting between the Father and the Son there rises the third Person, the Holy Spirit, who is the love of them both and who is one with them in the same nature. In a way characterized by both activity and blissful enjoyment, the Spirit embraces and penetrates the Father and the Son and all that lives in both of them with such great riches and joy that all creatures must remain silent before this, for the incomprehensible wonder which resides in this love eternally transcends the understanding of all creatures. But when a person understands this wonder and savors it without amazement, then has his spirit been raised above itself and been made one with the Spirit of God; it savors and sees-without measure, like God himself-the riches which it has itself become in the Unity of the living ground where it possesses itself in accordance with the mode of its uncreated bring.
Now this blessed meeting is actively renewed in us without ceasing in accordance with God's own mode of being, for the Father gives himself to the Son and the Son to the Father in an eternal sense of well-being and a loving embrace. This is constantly renewed in the bond of love, for just as the Father ceaselessly sees all things anew in the birth of the Son, so too are all things anew by the Father and the Son in the flowing forth of the Holy Spirit. This is the active meeting of the Father and the Son, in which we are lovingly embraced by means of the Holy Spirit in eternal love.
Now this active meeting and this loving embrace are in their ground blissful and devoid of particular form, for the fathomless, modeless being of God is so dark and so devoid of particular form that it encompasses within itself all the divine modes and the activity and properties of the Persons in the rich embrace of the essential Unity; it thereby produces a divine state of blissful enjoyment in this abyss of the ineffable. Here there is a blissful crossing over and a self-transcending immersion into a state of essential bareness, where all the divine names and modes and all the living ideas which are reflected in the mirror of divine truth all pass away into simple ineffability, without mode and without reason. In this fathomless abyss of simplicity all things are encompassed in a state of blissful blessedness, while the ground itself remains completely uncomprehended, unless it be through the essential Unity. Before this the Persons must give way, together with all that lives in God, for here there is nothing other than an eternal state of rest in a blissful embrace of loving immersion.
This is that modeless being which all fervent interior spirits have chosen above all things, that dark stillness in which all lovers lose their way. But if we could prepare ourselves through virtue in the ways I have shown, we would at once strip ourselves of our bodies and flow into the wild waves of the Sea, from which no creature could ever draw us back.
That we might blissfully possess the essential Unity and clearly contemplate the Unity in the Trinity-may the divine love grant us this, for it turns no beggar away. Amen. Amen." pg. 150-152 John Ruusbroec "The Spiritual Espousals" [The Classics Of Western Spirituality]
