Moreover, others illustrate it by a similitude, taken from a fountain, in which there is the spring in the bowels of the earth, the water bubbling out of the earth, and the stream diffusing itself in a perpetual course, receiving all it communicates from the fountain. I am sorry there is occasion to caution any against this method of explaining the doctrine of the Trinity. But these, and many other similitudes of the like nature, we find in the writings of some, who consider not what a handle they give to the common enemy. There are, indeed, in most of them, three things, which are said, in different respects, to be one; but we may observe, that all these similitudes, and others of the like nature, brought to illustrate this doctrine, lead us to think of the whole divided into those parts, of which they consist, whereof they take notice of the number three; or they speak of three properties of the same thing; and if their wit and fancy saw it needful to speak of more than three, the same method of illustrating would serve their purpose, as much as it does the end for which they bring it. Therefore I would conclude this head, by using the words of God to Job, _Who is this that darkeneth counsel by words without knowledge?_ Job xxxviii. 2. Who are these, that, by pretending to illustrate the doctrine of the Trinity by similitudes, do that, which, though very foreign to their design, tends to pervert it? 6. We shall now consider what general rules may be observed for our understanding those scriptures, on which our faith, with respect to the doctrine of the Trinity, is founded; and since it is a doctrine of pure revelation, as has been before observed, we must keep close to scripture, even to the words thereof, where they are express and distinct, as to this matter; and to consequences deduced from it, so far as they are just, and self-evident; and, at the same time, while we are sensible that we cannot comprehend this mystery, we must take care that we pretend not to be wise above what is revealed. Now there are some rules, which may be of use to us, in our enquiries into the sense of scripture concerning this doctrine; as,
