My pastor called me up last night and asked me to remind him why I had a problem with the sentiment that we are spirits who have souls and live in bodies. I answered that it’s gnostic at its core and it’s just not what we see in Scripture.
If we go back to the beginning it says that God formed man from the dust of the earth. Notice how it leads with that. Body first. Then he breathed the breath of life into this being and he became a living soul. He didn’t create a disembodied spirit and then make a body for it.
The whole man is body, soul, and spirit (I’m tripartite kind of a dude). Man is not fully man devoid of any one of these elements. Having a body is part of being human. Think about it like this: Could God have saved us apart from the Incarnation? Sure. He’s God, he can do whatever he wants. And yet the eternal Son took humanity upon himself in order to live righteously, suffer for our sins, die as an atoning sacrifice, and rise bodily in order to defeat death. Jesus’ body was essential to his mission.
