Since His body was reported as unrecognizable, and only appeared to those of faith, I would think spiritual. His risen body was no longer a body as we know bodies, bound by the dimensions of space and time. Paul's description of risen bodies, spiritual, not natural or physical, he even implies that these bodies are no longer flesh and blood. For Paul it is a mystery. When all is said and done I am satisfied that the D/R and giving of the Spirit was an eschatological event for which there is no language beyond analogy to describe the interaction of the eschatological and the historical.
