I. To premise some things which are necessary to be considered, with relation to it in general. II. We shall consider in what sense we are to understand the words _Trinity_, and _Persons in the Godhead_, and in what respect the divine Persons are said to be One. III. We shall prove that the Father, Son, and Holy Ghost, have distinct personal properties, and therefore that we have sufficient reason to call them Persons, in the Godhead, as they are in the first of these answers; and under this head shall consider what is generally understood by what is contained in the second of them, which respects the eternal generation of the Son, and the procession of the Holy Ghost; and what cautions we are to use, lest, by mistaking the sense thereof, we be led into any error, derogatory to, or subversive of the doctrine of the Trinity; and also shall endeavour to explain those scriptures, which are generally brought to establish that doctrine. IV. We shall endeavour to prove that these three Persons, especially the Son and Holy Ghost, are truly divine, or that they have all the perfections of the divine nature; and therefore that they are, in the most proper sense, the one only living and true God.[77] I. We shall premise some things which are necessary to be considered, with relation to the doctrine of the Trinity in general. And, 1. It is a doctrine of the highest importance, and necessary to be believed by all Christians, who pay a just deference to revealed religion. It may probably be reckoned an error in method to speak of the importance of this doctrine, before we attempt to prove the truth thereof: however, it is not altogether unjustifiable, since we address ourselves to those who believe it, hoping thereby to offer some farther conviction, or establishment, to their faith therein, as well as to others who deny it; we may therefore be allowed to consider it as an important doctrine, that we may be excited to a more diligent enquiry into the force of some of those arguments, which are generally brought in its defence.
