ISB ~ 1 Thessalonians 4 v14

Jesus died and rose again:The guarantee of our own bodily resurrection (Rom 8:11; CCC 989). See note on Lk 24:39.

• Christ is the pattern of our resurrection because he assumed flesh and rose again embodied in flesh. He is also the cause of our resurrection, for what was done by Christ’s humanity was done, not only by the power of his human nature, but also in virtue of his divinity. It was not merely his body that rose, but a body united to the Word of life (St. Thomas Aquinas, Commentary on 1 Thessalonians 4, 2).
