The Greek runs thus:—καὶ τὴν ἐν ἀλλήλαις περιχώρησιν ἔχουσι δίχα πάσης συναλοιφῆς καὶ συμφύρσεως. The term περιχώρησις, circumincessio, immanentia, was meant to express the peculiarity of the relations of the Three Divine Persons or Subsistences—their Indwelling in each other, the fact that, while they are distinct they yet are in one another, the Coinherence which implies their equal and identical Godhead. “In the Trinity,” says Bishop Bull (Defence of the Nicene Creed, bk. iv. ch. iv., secs. 13, 14), “the circumincession is most proper and perfect, forasmuch as the Persons mutually contain Each Other, and all the three have an immeasureable whereabouts (immensum ubi, as the Schoolmen express it), so that wherever one Person is there the other two exist; in other words They are all everywhere.…This outcome of the circumincession of the Persons in the Trinity is so far from introducing Sabellianism, that it is of great use, as Petavius has also observed, for (establishing) the diversity of the Persons, and for confuting that heresy. For, in order to that mutual existence (in each other) which is discerned in the Father, the Son, and the Holy Ghost, it is absolutely necessary that there should be some distinction between these who are thus joined together—that is, that those that exist mutually in each other should be different in reality, and not in mode of conception only; for that which is simply one is not said to exist in itself, or to interpenetrate itself.…Lastly, this is to be especially considered—that this circumincession of the Divine Persons is indeed a very great mystery, which we ought rather religiously to adore than curiously to pry into. No similitude can be devised which shall be in every respect apt to illustrate it; no language avails worthily to set it forth, seeing that it is an union which far transcends all other unions.”
