to orthodoxy

10. Dyohypostatic Theology
•Eusebius of Caesarea came closest to advocating the fullness of the theology
•One God, who is the beginning, or first principle - the cause of everything else that exists
•God is eternal and unbegotten, unknowable, and best described by negatives, such
as without source
•This God is the Father, the only He
•Along with this hypostasis (Person) there exists another hypostasis, the Son (Word,
Image, Wisdom, Power)
•The Father is the source of the Son’s being, but not be division or effluence
•The Son’s relationship of dependence excludes predicating “eternity” of him
•The son is subordinate to the Father and acts as Mediator
•Attributes the Old Testament Theophanies to the Son.
•The Incarnation was nothing new, but a continuation of the work as revealer,
teacher, and model
•Salvation becomes an order of will due to an impartation of knowledge
•There is no assumption of the human race by the Godhead
•The Incarnation, the cross,
and the resurrection results in no metaphysical change

11. •Miahypostatic Theology
•Represents the strict monotheism of Christianity.
•There is one God, who is one substance: one hypostasis, one
ousia, or for some, one prosopon
•God speaks the Word, His Son, and sends forth His spirit
•‘One’ is safe; ‘two’ is dangerous - plurality is located in the
Incarnation.
•The Son is God as the Father is God
•The Incarnation is decisive, marking a new stage in the existence
of the Logos in which God is united with a human nature
•It is the Incarnation that is subordinate; all scripture denoting a
subordination is assigned to the Flesh of the Incarnation
•Distinction occurs between the Uncreated and the created - the
uncreated is eternal while the created is temporal
•Both the Word and the creatures proceed from God, but in
different ways. The Son is begotten; creatures are from God’s will.
•Salvation is a divine act, by which humanity can become partakers of
the divine nature.
•Athanasius’ axiom of ‘God became man so that man might
become divine’ is representative of his early loyalty to this
theology
