John Thomas, the founder of the Christadelphian movement, wrote the following about the relationship between God the Father, the "Ancient of Days" and Jesus:
In this vision of the four beasts,
the matter is put somewhat differently. It is said the little horn prevailed
against the saints, "until the Ancient of Days came, and judgment
was given to the saints of the Most High." Now, who is the Ancient of
Days. The Deity: but how is He to "come"? In Jesus of Nazareth, who
is Deity manifested in our human nature—justified by spirit. Jesus himself
preached this coming in power and great glory. He said, "When the Son of
Man shall come in his glory, and all the holy angels with him, then shall he
sit upon the throne of his glory." that is the time when the Ancient of
Days comes; judgment shall then be given—to whom? "Judgment was given to
the saints of the Host [sic] High." The little horn made war against the
saints until judgment was given to them, they will no longer be trampled under
foot. When the time arrives for the Ancient of Days to manifest himself the
fortunes of the two parties will be reversed. The saints will have power put
into their hands, and they will execute judgment on the powers of the world.

Daniel and John [5th ed.; Birmingham: C.C. Walker, 1920], 11)
