Will men be circumcised after the Resurrection? Not sure exactly why I thought of this while taking a shower this morning, but I was wondering if the Catholic Church has ever weighed in on whether the bodies of men will be resurrected circumcised or not.  

I've read that a glorified body would be free from any imperfection, impairment.  That if one had a received a scar in this life, it would be gone in the next.  If you lost an arm in this life, that it would be present in the next.  So if you lose some foreskin in this life, will it be present in the next?

I've also read St. Augustine used as his rationale for many of his ideas about the Resurrection the notion our bodies would conform to Christ (He had some caveats as to whether we would all be men or all have beards). 

So, for the sake of deeper theological understanding, has the Catholic Church weighed in on this subject?
We won't know until the afterlife; the answer looks to be "no1"

The Fourth Lateran Council rules lean toward "no", as explained by Father Paul A Deffner, O.P.  


  THE SAME BODY
  
  Not only will our body be brought back to be reunited with the soul,
  but it will be the same body to which the soul was united before
  death.  As St. Paul declared (I Cor. 15:33): 
  
  
  This corruptible body must put on incorruption, and this mortal body
  must put on immortality.  
  
  
  Speaking on this point, the Fourth Lateran Council (1215)
  declared:   
  
  
  All men appear before the judgment seat of Christ with their own bodies, to give an account of their deeds."  
  
  
  During this life, whatever one has done (good or bad), the whole man (body and soul) has shared.  It is right, therefore, that both body and soul should share in the reward or punishment in the life to come.  
  
  ... When we say that the risen body will be the same body we had in this
  life, we mean this in the same sense as the body I have now is the
  same body I had 20 years ago.  


St Thomas Aquinas' on the glorified body

St Thomas Aquinas Summa presents that Christ's glorified body was his own body, glorified.  (Thus, if we are to be "like Him" our own body (glorified) is what we'll have at that point.)  


  
  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.
  (Summa Theologiae III, 54, 1)   
  But Christ's body after the Resurrection was truly made up of elements, and had tangible qualities such as the nature of a human body requires, and therefore it could naturally be handled. (Summa Theologiae III, 54, 2 ad 2) 
  


St. Thomas Aquinas at Summa Contra Gentiles, IV, 86 summarized, referring to the glorified body. 


  Thus also will his body be raised to the characteristics of heavenly
  bodies — it will be lightsome (clarity), incapable of suffering
  (impassible), without difficulty and labor in movement (agility), and
  most perfectly perfected by its form (subtlety). For this reason, the
  Apostle speaks of the bodies of the risen as heavenly, referring not
  to their nature, but to their glory.”  


And scriptural references ... 


  Matthew 13:43: “The just shall shine as the sun in the kingdom of
  their Father,”
  Wisdom 3:7: “The just shall shine, and shall run to and fro like sparks among the reeds.”  (Here clarity refers not being “clear” but to being “bright.”)


The four qualities of the glorified body are taught as Impassability, Subtlety, Agility, Clarity.  "Trimmed" and "not trimmed" didn't make the cut for that list.  

About Subtlety

How does "most perfectly perfected by its form" address circumcision, if at all?   Will scars be healed?  Maybe, or maybe not.  Depends on if a scar is a "trophy of victory" for a given person.    

St Thomas Aquinas, Summa Theologica, Questoin 1, Objection 4, Response 1 


  On the contrary, Our Lord said to Thomas (John 20:27): 
  
  
  Put in thy
  finger hither, and see My hands; and bring hither thy hand, and put it
  into My side, and be not faithless but believing.   
  
  
  I answer that, It was fitting for Christ's soul at His Resurrection to
  resume the body with its scars. In the first place, for Christ's own
  glory. For Bede says on Luke 24:40  
  
  
  that He kept His scars not from inability to heal them, "but to wear them as an everlasting trophy of His victory."
