The Son of the Son of the Father". Is this another form of "Father, Son and Holy Spirit?

"The Son of the Son of the Father". "The Son of the Son of the Father". I heard the phrase, "Son of the Son of the Father" recently and have never heard it before.

I'm guessing it is the same as "Father, Son and Holy Spirit (or Ghost)". Does anyone know? No, that would be nothing like the Biblical expression of the Trinity.

Ya see, the relationship of the second to first person in Who Is God is like the relationship of a son to a father. Neither is less nor more God for their choosing to describe their relationship in terms we humans can understand (somewhat.) The origin of cults and false religions is, every time, adding to that description. Thus, while Jesus is "the Son," some other fruitcake has apparently decided to claim that the Son has a "son" (much like Joseph Smith did in starting his Mormonism.) And the next step is to claim that the one coming up with this malarkey is that "son of the Son."

Promoting the self is what any cult or false religion is really all about. How do you know it's the truth? They promote God the Father, God the Son, and God the Holy Spirit at their own expense, minimizing their self.
