Chapter 1:5. Thou art my Son, etc. It is to be observed that Christ is called a Son when his prophetic office is referred to, ver. 2, when spoken of as a king, ver. 8, when his priesthood is mentioned, chapter 5:5, and when a comparison is made between him and Moses, chapter 3:6. But as a king over his people is he represented here as superior to angels; and David as his
type was also called a son because he was a king. Christ is said here to have derived his name by “inheritance” — from
whom? The Apostle refers throughout to the Old Testament; and what does Peter say That David, being a Prophet, knew that God
“would raise up Christ to sit on his throne,” Acts 2:30. Then the inheritance in this instance was
from David. Christ is God’s onlybegotten Son as to his divine nature; but he is also a Son in a peculiar manner, superior to all others, that is, as a Prophet, Priest,
and King. There were types of him in these offices; but they were only types, and therefore far inferior to him even as to
these offices. And angels never sustained such offices.
