Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 7:31-37

“That He might shew that all the members of His sacred body are divine and holy, even the spittle which loosed the string of the tongue. For the spittle is only the superfluous moisture of the body, but in the Lord all things are divine. It goes on, And looking up to heaven, he groaned, and saith unto him, Ephphatha, that is, Be opened.”
