When thinking of the mind letting go of the heart, the word “surrender” comes to mind. It is a dangerous word with necessary qualifications that sound like justifications to not surrender if they are listed.
Instead, what about poor bad body? At my mother in law’s funeral, the pastor said that our bodies get to be like old tents that should be discarded. This is not the traditional Christian approach. Our bodies are connected to our personhood and are just as much a part of us as our minds and hearts. By the way, I haven’t described what a mind or heart is with the same hesitancy I have about justifying not surrendering. Maybe later.
Many Christian groups do not believe in the bodily resurrection apparently. If it doesn’t get resurrected, then why was Jesus’ body gone from the tomb? If we are no longer connected to our bodies when we die, why are there incorrupt, miracle working, and fragrant myrrh streaming relics of dead Saints?
Then how can a body be bad? Because it is crippled by the bad decisions of the improperly ordered and not to-Christ (if not to human authority, not sure how exactly that one works) -surrendered mind in the heart. And it is still subject to decay, which does not have to be viewed as all bad.
But practically speaking, the body seems like a burden because it is the most dependent of our three faculties. It operates out of necessity for food and shelter. It was always meant to eat, but its food wasn’t always meant to be scarce or hard-earned. That is a result of the fall.
The body unites us to the rest of creation. If we were only spirits or souls we would exist as God does. For some reason he chose to reveal himself to us and to relate to us through created matter. It isn’t just a temporary stage in our development, even if it is stage 1 (life in the Church) and 2 (seeing God in created things) of the spiritual life. The third being contemplation of the Trinity. But Jesus, the second person of the Trinity, has a created, though resurrected body now. He took it with him. It still has a part to play, apart from necessity in the needy sense. Which brings to mind thoughts of the Trinity. Their relationship with each other is not of necessity. Necessity implies lack of freedom. As if they need each other for their existence. The Father doesn’t need the Son and the Spirit, even though there is no other option to having them. They freely relate to Him in perfect love and have no desire or need to do otherwise.
So even if the body feels like a burden, it will not always be so.
To complete the thought about literary characters personifying the heart, mind, and body, Mr. Granger brought out Star Trek‘s Kirk (which literally means church), Spock, and McCoy; The Lord of the Rings‘ Frodo, Sam (he’s actually the will – there I described a component of the mind), and Gollum (he said that’s a Catholic’s view of the body! My son likes the more functional trio of Aragorn, Legolas, and Gimli); Star Wars‘ Luke, Leia, and Han; and Twilight’s Edward, Bella, and Jacob, which last I don’t know.
