Aquinas, the Resurrection from the Dead, and Body Members

Thomas Aquinas believes that all of our body members will be restored in the resurrection, even if they are not used in the "afterlife." E.g., our kidneys, blood vessels, and genitalia. Now this restoration would present no problem for the righteous inhabiting the new earthly society of God's making (Rev. 21:1-5), but why heavenly creatures would have such members seems hard to comprehend. Of course, the pushback from the opposing side is that heaven and earth will unite one day--also that no one is going to heaven. But if some will be in heaven, as I believe, then human body parts appear to be redundant.

Reminds me of what one man said years ago in the field ministry: since flesh and blood cannot enter heaven, those who inherit the heavenly kingdom will just have fleshly bodies with no blood coursing through their veins. In any event, here are the sections from Aquinas:
