In light of recent discussions this quote from St Gregory Palamas may help provide some more patristic light on the issues.
Every created nature is far removed from and completely foreign to the divine nature. For if God is nature, other things are not nature; but if every other thing in nature, He is not nature, just as He is not a being if all other things are beings. And if He is a being, then other things are not beings. And if you accept this as true also for wisdom, goodness, and in general all things that pertain to God or are ascribed to Him, then your theology will be correct and in accordance with the saints. God both is and is said to be the nature of all beings, in so far as all partake of Him and subsist by means of this participation: not however by participation in His nature – far from it – but by participation in His energy. In this sense He is Being of all beings, the Form that is in all forms as the Author of form, the Wisdom of the wise and, simply, the All in all things. Moreover, He is not nature, because He transcends nature; He is not a being, because He transcends every being; and He is not nor does He possess a form because He transcends form. How, then, can we draw near to God? By drawing near to His nature? But not a single created being has or can have any communication with or proximity to the sublime nature. Thus if anyone has drawn close to God, he has evidently approached Him by means of His energy. In what way? By natural participation in that energy? But this is common to all created things. It is not, therefore, by virtue of natural qualities, but by virtue of what one achieves but virtue of free choice that one is close to or distant from God. But free choice pertains only to beings endowed with intelligence. So among all creatures only those endowed with intelligence can be far from or close to God, drawing close to Him through virtue or becoming distant through vice. Thus such beings alone are capable of wretchedness or blessedness. Let us strive to lay hold of blessedness.
Thus when you hear the fathers saying that God’s essence is imparticipable, you should realise that they refer to the essence that does not depart from itself and is unmanifest. Again, when they say that it is participable, you should realise that they refer to the procession, manifestation and energy that are God’s natural attributes. When you accept both statements in this sense you will be in agreement with the fathers.
And St Maximos also says, ‘He who is deified through grace will be everything that God is, without possessing the identity of essence.’ Thus it is impossible to participate in God’s essence… It is, however, possible to participate in the divine energy.
St Gregory Palamas, “Topics of Natural and Theological Science” Philokalia Vol 4
St Gregory also calls omnipresence an energy of God. We must not confuse the attributes or properties of God with His essence. We can be united to God in His energies even if we cannot participate in His essence. We can participate in omnipresence, omnipotence and all God’s attributes by the grace of God through His energies without needing to attain to His unapproachable essence. Man is created in God’s image and likeness to participate in divinity and so God’s attributes are not opposed to man, even though man is limited. God has His attributes by nature but this does not mean that man can not participate in them and be deified by grace. The energies of God are uncreated, and divine and, unlike the essence, can be participated in part without negating participation in the divine.
Some say that the union of divine and human is impossible; Christ cannot be God Incarnate. However, the Fathers have proved this reasoning false centuries ago and they speak well on the matter so nothing of substance can be added to them. Man is created in time, man is limited by time and space, man is limited in all ways but this does not mean that God cannot make man transcend himself and live in the limitless life of God. What contradiction can there be between God and His image? What opposition can creation have with God when is created in Him? Only sin is opposed to God and this is the result of the free choice of the sinner. Only unbelief in the power of God can deny man to participate in the infinite life of God and for the Divine to be united to Man in one Person, the Son of God.
