Institutions of Christian religion framed out of Gods word, and the writings of the best diuines, methodically handled by questions and answers, fit for all such as desire to know, or practise the will of God. Written in Latin by William Bucanus Professor of Diuinitie in the Vniuersitie of Lausanna. And published in English by Robert Hill, Bachelor in Diuinitie, and Fellow of Saint Iohns Colledge in Cambridge, for the benefit of our English nation, to which is added in the end the practise of papists against Protestant princes.

Is this difference rationall, essentiall, or reall?

It is not essentiall, as in the creatures, where euery one hath his proper essence or being, defined and circumscribed: for the essence of the Father is not one, and the essence of the sonne another, and of the holy Ghost another: but one and the same, which the Father doth wholly communicate to the Sonne; the Father and the Sonne to the holy Ghost. Not onely in reason, because not in notion, or mind, or onely in word is he called Father, Sonne, and holy Ghost: neither respectiuely or by relation: as one man may both be, and be called a father and a sonne. But it is reall, yet altogether incom∣prehensible, because each person hath his own peculiar definition, or his essentiall and incommunicable proprietie, and differs from another not in essence, but in the manner of subsisting.
