You should read S.T., part 3, Ques 54, ans 1 and following. Thomas explains that Christ’s Resurrected Body is a real physical body, just as I said, and physical just as I said, but that it is a glorified body no longer restricted by the limitations imposed on worldly matter.

One quote used by St. Thomas is especially enlightening. " As Damascene says (De Fide Orth. iv): that is said to rise, which fell. But Christ’s body fell by death; namely, inasmuch as the soul which was its formal perfection was separated from it. Hence, in order for it to be a true resurrection, it was necessary for the same body of Christ to be once more united with the same soul. And since the truth of the body’s nature is from its form it follows that Christ’s body after His Resurrection was a true body, and of the same nature as it was before…"
The Blackfriars edition translates " true body" or " body " as a physical body.
The Blackfriars edition of the Summa has an explanatary footnote that reads:
" The four endowments of a glorified body according to the Scholastic theologians are
impassibilitas, as immunity from suffering or hurt; *subtilitas, * an absence of lumpish density;
agilitas, a swiftness of response to spirit; and
clrirtas, or lightness. Then it refers the reader to the Supplemtum of the Summa Ques 83 - 85. These explain subtlety, agility, clarity as regards resurrected bodies.

To sum up, God created two orders of creatures, the material and the spiritual ( i.e. composed of no matter or immaterial, God, angels, and the human soul ). There is no third substance. So Christ’s resurrected body, which is what we receive in Communion, is either material ( physical ) or spiritual, there is no third option. And since no body is spiritual, it must be, as the Fathers say, that Christ’s resurrected body is material or physical, but a physical body which transcends the limitations of earthly bodies.
And I agree these things have not been taught to ordinary Catholics sufficiently. It is possible, probable that most Catholics accept it in that same simple faith possessed by the Apostles. " …where shall we go, we believe you are the Son of the living God and you have the words of life…? "
