I do affirm that. The "link" that I'm talking about is the "link" in the diagram which is commonly used to visualize the Trinity. By saying a person of the Trinity is "linked" to His substance, I'm not saying the link is a medium between the two that unites them to each other. I'm simply distinguishing them from each other, not separating which would result in parts in God. The "link" is meant to clarify just that.
Say there were a diagram that showed all human persons with lines connecting to the word "human." The persons are different from each other, but they are all human. It would be odd to say that an individual person is "linked" to "human." It's what they are, not what they are linked to.
Oh! I think I see my problem now. It has been my understanding that "God" in the middle of the diagram means only His
substance and not both His substance and persons. But this still leaves me with the same problem that I've presented above concerning the statement that one person of the Trinity
is "God." I obviously don't understand the meaning of the word "is" there.
I think it is odd that the Bible can speak of God as both "Him" and "Them." In the Genesis 1:26 God said (in
plural) "Let
us make man in
our image, after
our likeness," and in Genesis 3:22 God said, ""Behold, the man has become like one of
us in knowing good and evil." So, if "they" refers to the three
persons of the Trinity, then
who (not
what) does "He" refer to? Is it the Father? Or is it a reference to the
name of God ("I am that I am")?
