John 3:12,13 - Coke's Commentary on the Holy Bible

If I have told you earthly things,— "If you believe not these obvious truths concerning the spiritual nature of God's kingdom, and the qualifications of his subjects, how shall you believe the more sublime doctrines of religion, which I am come to teach you?" OurLord goes on, "In the mean time, you may safely receive my instructions; for I am vested with an authority, and endued with gifts far superior to all prophets that have ever appeared; No man hath ascended up to heaven," &c. Perhaps Jesus mentioned his coming down from heaven, to put the Jewish doctor in mind of the acknowledgment with which, at the beginning of their interview, he had addressed him, namely, that he was a teacher come from God. This passage is a plain instance of what is usually termed the communicationof properties between the divine and human natures, whereby what is proper to the divine nature is spoken concerning the human, and what is proper to the human, is spoken of thedivine. Thus when it is said (1 Corinthians 2:8.) The Lord of glory was crucified, and (Acts 20:28.) when he is called God, who purchased the church with his own blood,—the meaning is not that he, as the Lord of glory, was crucified, or, as God, shed his blood, as if the Divine nature could be crucified and bleed; but that the person, who was the Lord of glory in one nature, was crucified in the other; and the person, who was God in one nature, purchased the church with his own blood, which belonged to his other nature: so when it is said, The Son of man is in heaven, the meaning is not that he, as the Son of man, was there while he was on earth; but that he, who was here in his human nature, was there in his divine.
