In order therefore for a man to understand, or even to know of, God, he must have a god-like spirit communicated to him, wherewith, as with an inward eye, which is both eye and light, he sees the spiritual truths.

Now I have no objection to his calling this spirit a 'person,' if only the term 'person' be so understood as to permit of its being partaken of by all spiritual creatures, as light and the power of vision are partaken of by all seeing ones.

But it is too evident that Sherlock supposes the Father, as Father, to possess a spirit, that is, an intellective faculty, by which he knows the Spirit, that is, the third co-equal Person; and that this Spirit, the Person, has a spirit, that is, an intellective faculty, by which he knows the Father; and the 'Logos' in like manner relatively to both.

So too, the Father has a 'logos' with which he distinguishes the 'Logos';--and the 'Logos' has a 'logos', and so on: that is to say, there are three several though not severed triune Gods, each being the same position three times 'realiter positum', as three guineas from the same mint, supposing them to differ no more than they appear to us to differ;--but whether a difference wholly and exclusively numerical is a conceivable notion, except under the predicament of space and time; whether it be not absurd to affirm it, where interspace and interval cannot be affirmed without absurdity--this is the question; or rather it is no question.

Nor do we divide the substance, but unite these three Persons in one numerical essence: for we know nothing of the unity of the mind, but self-consciousness, as I showed before; and therefore as the self-consciousness of every Person to itself makes them distinct Persons, so the mutual consciousness of all three divine Persons to each other makes them all but one infinite God: as far as consciousness reaches, so far the unity of a spirit extends, for we know no other unity of a mind or spirit, but consciousness.
But this contradicts the preceding paragraph, in which the Father is self-conscious that he is the Father and not the Son, and the Son that he is not the Father, and that the Father is not he.
