I think we'd call this a bit confused. At least by way of theological development, the ontology of participation tends to erase the Creator-creature distinction.
It sounds somewhat close to the Eastern doctrine of theosis, in which "sanctity" (or the process of sanctification) is a matter of literal participation in the divine perfection.
There's more than a little Platonism here, I suspect. In this view, God is the "highest" of beings, and has all qualities in their highest measure or degree. Observe here a lack of the true and radical "Creator-creature distinction."
Sometimes, it is claimed that 2Pet.1:4 supports the notion of participation, because of the language, "partakers of the divine nature." But this is manifestly not the case. The is unquestionably blessings that flow from "partaking" of the divine nature, including resemblance. However, that in no wise leads to the conclusion that we thus begin to share ontologically in the ineffable being of God.
By way of analogy, by eating a crust of bread it is true that I am "partaking" of the bread-nature. However, whatever the blessings accrue to me by this partaking (and there is a grain of truth to the expression: "you are what you eat," cf.1Cor.10:17), still I am not becoming "bread" myself. Not even a little bit.
And this is the case in regard to a thing with which I do share an ontological relation. The bread and I are both carbon-based. The living stuff that went into the bread is materially connected to my flesh already. But I am not adopting breadlike qualities, nor is the bread that I eat adopting human qualities (as if the question were one of direction-of-flow).
By sanctification, we are not entering into divine ontology. Neither is God absorbing us into his being. We are being transformed and conformed to the perfect human-image of Christ, the last Adam; but an image is still image-like, a simulacrum, a type. There is One, and one only, who engages in a unique sort of "participation" in the divine--namely Christ Jesus. And the reason he does so is because he IS the eternal, divine Son. He partakes of our nature, Heb.2:14, even to associating it with his Person. But his human remains human, and his divine remains divine; yet they are in harmony (not conflict) within the Person.
We, by comparison, are never going to have "two natures, in one person." Our tangible union with Christ is by virtue of his humanity; our legal union is by virtue of his Person.
