By the Virtue of the Spirit
Because christologically the communication of properties is not an alteration or exchange of what is proper to the natures but a denotation of what is true of the Person, the wholeness of Christ, in both his divinity and humanity, is personally present, yet non-physically, by the virtue of the Spirit.
