Two fluids which can't be mixed, where you cannot dissolve one in the other, are termed immiscible.
If you pour immiscible fluids in the same container and stir vigorously, they will be together, but stay separate, and create an emulsion.

Now, "numinous" means "permeated with the presence of divinity", so the situation you're describing might be termed a "numinuos emulsion".
If the literal, chemical answer is too clinical for you, there are some other options available from Catholic theology.
The words "indwelling", "circumincession” or "perichoresis", and "co-inherence" (all synonyms) are typically applied in the study of the "Trinity", and describe how the three persons of the Catholic deity can exist "together but separately" in one being.
But the words have also been applied to the relationship between the divine spirit and the body and spirit of a living person:
The crucial point, in a word, is that the relation to God, and to others in God, that establishes the individual substance in being is generous. The relation itself makes and lets me in my substantial being be. This “letting be” implies a kind of primordial, ontological “circumincession,” or “perichoresis,” of giving and receiving between the other and myself. What I am in my original constitution as a person has always already been given to me by God and received by me in and as my response to God’s gift to me of myself ― indeed, has also, in some significant sense, been given to me by other creatures and received by me in and as my response to their gift to me.
