It is clear from the Scriptures that Christ hungered, thirsted, and got tired, and bled. All of these things mean that his body, before the resurrection, contained cells that could break down and dis-integrate just like ours. It would be the teaching of the Scriptures that Christ's body could not see corruption (decomposition after death) in the Tomb, however.
The Roman Catholics had a tradition that some Byzantine Empress gave Charlemagne the Holy Foreskin as an incorrupt relic. The RC's fought over which relic was the real Holy Foreskin for centuries, and then placed a ban of excommunication on anyone who mentioned it for a while.
