Theophylact of Ohrid
Catena Aurea · Johannesevangelium 8
Then said they unto him, Where is thy Father? Jesus answered, Ye neither know me, nor my Father: if ye had known me, ye should have known my Father also. These words spake Jesus in the treasury, as he taught in the temple: and no man laid hands on him; for his hour was not yet come.
Let the Arian blush: for if, as he says, the Son be a creature, how does it follow that he who knows the creature, knows God? For not even by knowing the substance of Angels, does one know the Divine Substance? Forasmuch therefore as he who knows the Son, knows the Father, it is certain that the Son is consubstantial with the Father.
