"...Behold, I have said this: that the contemplative lover of God is united with God through an intermediary, and also without intermediary, and thirdly, without difference or distinction; and this I find in nature, and in grace, and also in glory...We must all be lifted up above ourselves into God, and become one spirit with God in love; and then we shall be blessed. And therefore mark my words and my meaning, and understand me aright as to what is the condition and the way to our eternal blessedness...
OF THE UNION THROUGH AN INTERMEDIARY
And next, I will say that all good men are united with God through means. These means are the grace of God, and the sacraments of Holy Church, and the Divine virtues, faith, hope and charity, and a virtuous life according to the commandments of God; and to these there belongs a death to sin and to the world and to every inordinate lust of nature. And through these, we remain united with Holy Church, that is, with all good men; and with these, we obey God, and are one will with Him, even as an orderly convent is united with its Superior...
OF THE UNION WITHOUT INTERMEDIARY
These same interior, enlightened persons have the love of God before them in their inward vision whenever they want, as drawing or calling in towards unity. For they see and feel that the Father with the Son by means of the Holy Spirit stand embraced with all the elect and are brought back with eternal love into the unity of their nature. This unity is constantly drawing or calling in all that has been born out of it naturally or by grace. And therefore these enlightened people are lifted up with free mind above reason to a bare vision devoid of images. There lives the eternal invitation of God’s unity, and with imageless naked understanding they go beyond all works and all practices and all things to the summit of their spirit. There their naked understanding is penetrated with eternal clarity as the air is penetrated by the light of the sun. The bare elevated will is transformed and penetrated with fathomless love just as iron is penetrated by the fire. And the bare elevated memory finds itself caught and established In a fathomless absence of images. Thus the created image is united threefold wise above reason to its eternal image, which is the source of its being and of its life...
Christ prayed that He should be in us, and we in Him. This we find in many passages in the Gospel. And this is the union that is without intermediary, for the love of God is not only out-flowing, but it is also drawing into unity. And those who feel and experience this become interior, enlightened men. There the faculties are raised above all practices to the bareness of their very essence. There the faculties become simplified above reason in their essence and because of this they are filled and overflowing. For in this simplicity the spirit finds itself united with God without intermediary
OF THE HIGHEST UNION, WITHOUT DIFFERENCE OR DISTINCTION
And after this there follows the union without distinction. For you must apprehend the Love of God not only as an outpouring with all good, and as drawing back again into the Unity; but it is also, above all distinction, an essential fruition in the bare Essence of the Godhead. And in consequence of this enlightened men have found within themselves an essential contemplation which is above reason and without reason, and a fruitive tendency which pierces through every condition and all being, and through which they immerse themselves in a wayless abyss of fathomless beatitude, where the Trinity of the Divine Persons possess Their Nature in the essential Unity. Behold, this beatitude is so onefold and so wayless that in it every essential gazing, tendency, and creaturely distinction cease and pass away. For by this fruition, all uplifted spirits are melted and noughted in the Essence of God, Which is the superessence of all essence. There they fall from themselves into a solitude and an ignorance which are fathomless; there all light is turned to darkness; there the three Persons give place to the Essential Unity, and abide without distinction in fruition of essential blessedness...for that beatific state, which is the fruition of God and of all His beloved, is so simple and onefold that therein neither Father, nor Son, nor Holy Ghost, is distinct according to the Persons, neither is any creature. But all enlightened spirits are here lifted up above themselves into a wayless fruition, which is an abundance beyond all the fulness that any creature has ever received or shall ever receive. For there all uplifted spirits are, in their superessence, one fruition and one beatitude with God without distinction; and there this beatitude is so onefold that no distinction can enter into it. And this was prayed for by Christ when He besought His Father in heaven that all His beloved might be made perfect in one, even as He is one with the Father through the Holy Ghost: even so He prayed and besought that He in us and we in Him and His heavenly Father might be one in fruition through the Holy Ghost. And this I think the most loving prayer which Christ ever made for our blessedness.
For this is the inmost life of the spirit; and, in the enlightened and uplifted man, the life of the senses adheres to the spirit. And so his sensual powers are joined to God by heart-felt love, and his nature is fulfilled with all good; and he feels that his spiritual life adheres to God without means. And thereby his highest powers are uplifted to God in eternal love, and drenched through by Divine truth, and established in imageless freedom. And so he is filled with God, and overflowing without measure. In this inundation there comes to pass the essential outpouring or immersion in the superessential Unity; and this is the union without distinction, of which I have often told you. For in the superessence all our ways end. If we will go with God upon the highway of love, we shall rest with Him eternally and without end: and thus we shall eternally go forth towards God and enter into Him and rest in Him..."
