Now if there are three Persons of infinite and the same attributes, dismiss two, and you lose nothing but a numerical phantom." The answer to this must commence by a denial of the premisses 'in toto': and this both Bull and Waterland have done most successfully.

But I very much doubt, whether Sherlock on his principles could have evaded the Unitarian logic.

In fact it is scarcely possible to acquit him altogether of a 'quasi-Tritheism'.

'For like as we are compelled by the Christian verity to acknowledge every Person by himself to be God and Lord';-- (That is, by especial revelation.) 'So are we forbidden by the Catholic religion to say, There are three Gods, or three Lords.' That is, by the religion contained in, and given in accompaniment with, the universal reason, 'the light that lighteth every man that cometh into the world'.

This Creed (Athanasian) does not pretend to explain how there are three Persons, each of which is God, and yet but One God, (of which more hereafter,) but only asserts the thing, that thus it is, and thus it must be if we believe a Trinity in Unity; which should make all men, who would be thought neither Arians nor Socinians, more cautious how they express the least dislike of the Athanasian Creed, which must either argue, that they condemn it, before they understand it, or that they have some secret dislike to the doctrine of the Trinity.
The dislike commonly felt is not of the doctrine of the Trinity, but of the positive anathematic assertion of the everlasting perdition of all and of each who doubt the same;--an assertion deduced from Scripture only by a train of captious consequences, and equivocations.
