There is no reason this should be a problem. God is not divided into parts. He is Simple. This is simply an explanation of how He can interact with creation, including Man, and still be the Transcendent God. It's nothing more than that.
Those are your words. The words that are the subject of discussion are these:
"That supremely Divine light is neither a created thing, nor the essence of God, but is rather uncreated and natural grace, illumination, and energy which everlastingly and inseparably proceeds from the very essence of God."
"There is an unconfused union of God's essence and energy, so is there also an undivided distinction between them, for, among other things, essence is cause while energy is effect, essence suffers no participation, while energy is communicable."
As with any doctrine, Catholics look to whether it can be found in (1) Scripture, (2) Tradition, and (3) the teachings of the Magisterium.
Can the above statements be found in:
(1) Scripture? No.
(2) *Tradition? * No.
(3) The teachings of the Magisterium? No.
Can the denial of the above statements be found in:
(1) Scripture? Not explicitly, since the doctrine wasn't invented for another 1300 years, but the statements that Scripture makes concerning God's nature ("I AM WHO I AM", "God is Love", "God is Light", "God is Spirit") express a simplicity that isn't compatible with God being a "union" of two different things.
(2) Tradition? The Church Fathers have always upheld the simplicity of God. Saint John of Damascus says that God is "simple" and "uncompound". newadvent.org/fathers/33041.htm Now a union is by definition compound. For example, Saint John of Damascus later says of the Hypostatic Union of our Lord Jesus Christ, "He has two natures but only one subsistence compounded of both." newadvent.org/fathers/33043.htm
Saint Cyril of Alexandria is even more to the point: "For if one is not too poorly endowed with the decency which befits wise men, one will say that the divine being is properly and primarily simple and incomposite; one will not, dear friend, venture to think that it is composed out of nature and energy, as though, in the case of the divine, these are naturally other; one will believe that it exists as entirely one thing with all that it substantially possesses. Thus, if anyone says that his energy, that is, his Spirit, is something created and made, even while it belongs to him in a proper sense, then the Deity, surely, will be a creature, given that his operation is no other thing than he himself." bekkos.wordpress.com/2009/06/22/st-cyril-on-divine-simplicity/
(3) The Magisterium? The Synod of Rheims defined that God is His attributes. The Magisterium defined that God is "one absolutely simple essence" at the Fourth Lateran Council in 1215. ewtn.com/library/councils/lateran4.htm#1 This rules out the possibility of God being a "union" of essence and energy, rather than one absolutely simple essence.
