Theodoret of Cyrus, on Heb 2:11

“For both he that sanctifieth, and they who are sanctified, are all of one. For which cause he is not ashamed to call them brethren, saying:”

“"The one who sanctifies and those who are sanctified have all one origin." This is a reference to the humanity of the one who sanctifies, for the assumed nature is created. The creator of him and of us is one. We are sanctified through him. Now if the heretics wish to understand this of the divine nature, let them not do so in such a way as to lessen the glory of the only begotten. For both we and he have one Father; but it is clear that he is Son by nature, we by grace. The fact that it says, "He sanctifies, but we are sanctified," teaches us this difference.”
