Can One Justifiably Infer Jesus' Resurrection on the Basis of Empirical Evidence?

1. If it cannot be established that Jesus transformed into a supernatural body after He rose from the dead, then the Resurrection cannot be established. 
2. If cannot be established that Jesus transformed into a supernatural body after He rose from the dead. 
3. Therefore, the Resurrection cannot be established. 

It seems to say that even if Jesus somehow survived, there is no evidence whatever that He rose in an immortal/indestructible body. Therefore, the argument grants a resurrection of sorts, but not the supernatural kind the New Testament describes. Thus, the divine claims of Christ cannot be established by resurrection evidence. 

This argument seems to assume that one must establish proof of Jesus' resurrection by proving He had a supernatural body after He was raised. This really isn't an argument against Jesus' resurrection. Rather it's an attempt to prove that you can't justifiably infer Jesus' resurrection on the basis of empirical evidence. It's an attempt, not to refute the resurrection of Jesus, but to undercut a historical argument for Jesus' resurrection.
