Christ’s glorified body is physical, of course. It simply is no longer limited by space and time and so on. It is physical in the sense that it can be naturally manifested in physical reality, but it is no longer bound by laws of nature or science.
The way I see it, a glorified human body is one in which physical and spiritual are made to be in perfect union. This is seemingly part of the reason why Heaven and Earth must “pass away” and be renewed: in order for a finite being to have a physical body and a spirit existing in perfect unity, reality cannot be the same as our current universe.
While the actions of the Father are inseparable from the actions of the Son or Holy Spirit, the actions of our soul are not yet inseparable from the actions of our body. We can form contradictions between the two. Only when our body and soul act perfectly together can we perfectly love God. And so it makes sense that we must be physical in at least one sense.
Because God is not finite, though, He Himself - the glorified Christ - can manifest Himself fully and physically in His truly glorified body right now. THIS, at least partly, is why His apostles didn’t recognize Him - His body was physical, but now His very body was no longer ONLY physical. They looked upon not only a physical body, but also its perfect union with spirit and divinity.
He could appear in locked rooms and such an violate “laws” of science. This could be seen perhaps, scientifically speaking, as Christ’s physical body transcending normal three-dimensional movement.
So while Christ’s presently glorified body IS physical, it is not MERELY physical.
