Why was Origen accused of making the Son subordinate to the Father?

Origen was accused of making the Son subordinate to the Father because his theological system described the divine Logos—the second hypostasis (Person) of the triad—as being subordinate to the Father, even while maintaining that the Son remained on the divine side of the gulf between the infinite Creator and finite creation.1

Critics viewed this hierarchical distinction as a precursor to Arianism, a 4th-century heresy that denied the Father and the Son were of the same substance. Because Origen wrote his theological works long before the later conciliar definitions regarding the Trinity and the Person of Christ were established, he operated in a period where doctrine was more open to speculation. Consequently, his efforts to articulate the relationship between the members of the divine triad were later interpreted by opponents as compromising the full equality of the Son with the Father.23
