The statement by St. Athanasius of Alexandria, "The Son of God became man, that we might become God", indicates the concept beautifully. II Peter 1:4 says that we have become "...partakers of divine nature." Athanasius amplifies the meaning of this verse when he says theosis is "becoming by grace what God is by nature" (De Incarnatione, I). What would otherwise seem absurd, that fallen, sinful man may become holy as God is holy, has been made possible through Jesus Christ, who is God incarnate. Naturally, the crucial Christian assertion, that God is One, sets an absolute limit on the meaning of theosis - it is not possible for any created being to become, ontologically, God or even another god.
It is not, in short, anything like it is being portrayed. Read more here.
Ontology
From Wikipedia, the free encyclopedia
~~~~~This article discusses ontology in philosophy. For the term in computer science, see ontology (computer science). In philosophy, ontology (from the Greek ὄν, genitive ὄντος: of being (part. of εἶναι: to be) and -λογία: science, study, theory) is the most fundamental branch of metaphysics. It studies being or existence and their basic categories and relationships, to determine what entities and what types of entities exist. Ontology thus has strong implications for conceptions of reality.
Some philosophers, notably of the Platonic school, contend that all nouns refer to entities. Other philosophers contend that some nouns do not name entities but provide a kind of shorthand way of referring to a collection (of either objects or events). In this latter view, mind, instead of referring to an entity, refers to a collection of mental events experienced by a person; society refers to a collection of persons with some shared characteristics, and geometry refers to a collection of a specific kind of intellectual activity. Any ontology must give an account of which words refer to entities, which do not, why, and what categories result.
When one applies this process to nouns such as electrons, energy, contract, happiness, time, truth, causality, and god, ontology becomes fundamental to many branches of philosophy.
Ontology has one basic question: "What actually exists?" Different philosophers provide different answers to this question.~~~~~
So we see Anthanasius is trying to discuss this issue with an eye on Ontology...Ontology apparently is a branch of Plato's Philosophy...
Would seem pagan philosopy would have nothing in common with the Spiritual realm of God, but, oh well...
But what remains is that Athanasius in not trying to give an explanation because Ontology is nothing more than a philosophy...But what he is doing is denying the statement in your Catechism that you will become gods but you must trust Athanasius on this philosophy becauce HE understands philosophy, and you don't...
