User blog comment:Malthael Archangel of Death/Cosmic Entity vs God/@comment-34326521-20171106200633

God rebuilt Castiel. Not once did he use the term "resurrect"; only the fanbase did. However, all the Cosmic Entity said is that God has no pull in the Empty. It also implied that a deal can be made with it to recover something from the Empty. Furthermore, in S5, we saw that when people die, their souls are not immediately taken to the afterlife, as was the case with one of Famine's victims. No reason why that couldn't happen with angels as well.
