Jesus Christ is Dead

I'm trying to apply more logical reasoning in my approach to religion so let's see how well I can do.

P1: To be physically alive in Christianity, a body and soul must be united.

P2: During his burial, Jesus' body and soul were separated and thus he was dead.

P3: Jesus was resurrected (made alive) when his buried body was reunited with his soul

P4: God is spirit and he resides in a spiritual dimension - Heaven is not a physical space where bodies exist

P5: Jesus after his resurrection, ascended to heaven and thus abandoned his body

Conclusion: Jesus is physically dead presently, as dead as he was during the time of his burial in the tomb.

Edit: So it seems like I was mistaken with premise 4 which leads to a ln error in premise 5. Heaven, in Christian doctrine, is apparently a physical space containing at least 3 physical bodies - Enoch, Elijah and Jesus.
