I am already not certain of the meaning of a phrase.  The second article says...

II.

In this divine and infinite Being there is the Father, the Word, and the Holy Spirit; each having the whole divine Essence, yet the Essence undivided; all infinite without any beginning, therefore but one God; who is not to be divided in nature, and being, but distinguished by several peculiar relative properties.

1 Cor. 1:3; John 1:1, 15:26, Exod. 3:14; 1 Cor. 8:6

I suspect that the phrase "but distinguished by several peculiar properties" has something to do with the fact that God is three persons.  The three persons are named at the beginning of the article as "Father, Word, and Holy Spirit."  So if we look at what "distinguishes" then from one another, this article uses the distinguishes them as "several relative properties."  This seems a wierd way to say three different persons.  The concept of three persons I can grasp, what in the world is "several relative properties?"
