EWTN.com - Human and divine nature: "Human and divine nature
When Jesus was on earth He had two natures, human and divine. After the Resurrection did His human spirit cease to be and now He needs/has only His divine nature? Related to this question: I'm wondering if our human spirits become divine spirits after death through a purification by God and a joining in His life. Thank you.
Answer by David Gregson on 11/6/2008:
'Jesus Christ is the same yesterday and today and forever' (Heb 13:8). No, He didn't lose His human nature when He died, or when He rose again. He came as man to overcome death as a man. If He weren't still a man when He rose from the dead, He wouldn't have overcome death. It's because He is still a man, as well as God, that we humans can share in His victory over death, by our relationship with Him (through faith and the sacraments) as He still is today.
The faithful will become divine in a sense, a future for which we were prepared in being created in God's image, but we will never become the Creator and cease to be creatures."
