Terms have both a reference and a sense. The reference of a term is the thing it refers to while the sense of a term is the means by which it refers to that thing (i.e. it’s content). If Jaco Gericke is going to succeed in his argument he will need to demonstrate first that the sense of the term “Yahweh” in scripture unilaterally fails to refer to the same being that Christian theologians and philosophers refer to with the term “God” or “Trinity” or “Father of our Lord Jesus Christ”. Second, he will have to provide reasons to think that no God exists under either the ancient Israelite or contemporary theological/philosophical description.
Gericke didn’t even attempt to do the second task and he failed to accomplish the first.
