Except Christianity isn’t Hinduism, nor is it actually taught that our ultimate form is to be souls without bodies. That form is certainly an incomplete one. The Catholic article erroneously quotes the following scripture in support of the Spirits being alive. While spirits are certainly not “dead” by the modern definition, they are not “alive” since to be dead in the first place means a separation from the body.
The verse they quoted is in reference to the resurrection of the dead. The body and soul being reunited at the great resurrection at the end of time.
Mat 22:31-32 But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, (32) I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.
I was merely pointing out the similarity of the understanding that the soul is alive, and the earthly body is a covering like a tent.
You see it differently, that’s all.
