Everybody is correct about the Divinity of Christ remaining intact. Otherwise, it could not be said that God died for our sins, and we would be left with nothing but heresy and damnation.
His Divinity is inseparable from His humanity. The humanity of Christ is made of a human body and a human soul, just like all other men, for He was true man. His human body is Divine and His human soul is Divine, as He is true God, even in His humanity.
His human soul, which is Divine, separated from His body, which also is Divine, at His death. His Divine and human soul descended to the dead, while His Divine and human body remained in the sepulcher.
He then willed for His soul and body to be reunited, neither one having ever been any less God or man.
