The King of the universe will raise us up to an everlasting renewal of life, because we have died for his laws. 538 One cannot but choose to die at the hands of men and to cherish the hope that God gives of being raised again by him. 539
Catechism number 999
How? Christ is raised with his own body: "See my hands and my feet, that it is I myself";551 but he did not return to an earthly life. So, in him, "all of them will rise again with their own bodies which they now bear," but Christ "will change our lowly body to be like his glorious body," into a "spiritual body":552
But someone will ask, "How are the dead raised? With what kind of body do they come?" You foolish man! What you sow does not come to life unless it dies. and what you sow is not the body which is to be, but a bare kernel ....What is sown is perishable, what is raised is imperishable.... the dead will be raised imperishable.... For this perishable nature must put on the imperishable, and this mortal nature must put on immortality.553
