The God of our fathers raised up Jesus
Not from the dead, though this was true; but called him to the work and office of a Saviour, inverted him with that office, and sent him to perform that work; so that this refers rather to the incarnation of Christ, in consequence of the ancient council and covenant of grace: and this the apostles attribute to God the Father, under the character of "the God of our fathers, Abraham, Isaac, and Jacob", as in ( Acts 3:13 ) , to show that they did not bring in and worship any strange God; nor introduce any novel doctrine; or speak of any other Saviour or Redeemer, than he whom the God of their fathers had appointed, and who was made known to them, whom they looked for and believed in, and were justified and saved by:
whom ye slew and hanged on a tree;
this is said in defence of themselves, being charged that they intended to bring this man's blood upon them; they therefore insist upon it that they had slain Jesus whom God raised up, inasmuch as they had condemned him to death in their sanhedrim, and had urged and importuned Pilate to crucify him, and had imprecated his blood upon them and on their children; and were not content to put him to any kind of death, but insisted on his being crucified, or hanged on a tree; that is, stretched out upon the cross, which was both a painful and shameful death, to which they were manifestly accessary, and therefore justly charged with it.
