I shall endeavour to persuade you that there is, and that there is said to be, another God and Lord subject to the Maker of all things; who is also called an Angel, because he announces to men whatsoever the Maker of all things, above whom there is no other God, wishes to announce to them;....that he who is said to have appeared to Abraham, and to Jacob, and to Moses, and who is called God, is distinct from Him who made all things, I mean numerically, not in will.
Justin Martyr, Dialogue with Trypho, 56 (mid-second century Rome)
Origen: Is the Son distinct from the Father?
Heraclides: Of course. How can he be Son if he is also Father?
Origen: While being distinct from the Father is the Son himself also God?
Heraclides: He himself is also God.
Origen: And do two Gods become a unity?
Origen: Do we confess two Gods?
Hearclides: Yes. The power is one.
Origen: But since our brothers take offense at the statement that there are two Gods, we must formulate the doctrine carefully, and show in what sense they are two and in what sense the two are one God.
Origen, Dialogue with Heraclides 124 (early third century Alexandria)
