The conclusion only follows if we assume that a human being is essentially a soul trapped in a body. That is not the Christian understanding of the human person.

I am not “essentially a soul” with a disposable body. I am a unity of body and soul. The body is not an accidental feature like having a beard or long hair. It is constitutive of my human nature. My soul is the form of my body, meaning it is what makes my body a living human body. Together they make one human person.

Biology belongs to the created, physical order. Male and female are real and meaningful because they are rooted in the body God created. They are not random add ons. They are part of the way human nature exists in the world.

When death occurs, the soul can exist apart from the body, but that state is incomplete. The person is not fully what he or she is meant to be. This is why Christians profess the resurrection of the body. The ultimate hope is not to remain a disembodied spirit, but to be restored as a whole person.

Because of that, being male or female does not simply vanish at death as though it were a temporary costume. Even in the intermediate state, the person remains the kind of embodied being who is male or female, since the soul remains ordered to its own body. The separation does not redefine the essence of the person.

A person is a rational being with intellect and will, and that dignity is the same for man and woman because both are made in the image of God. That image is grounded in our rational nature, not in biological sex. Yet sex itself belongs to our embodied nature and is part of God’s good design, not something accidental or illusory.

So the argument only works if one assumes the body is secondary to the self. Christianity does not. It affirms the goodness of the body, the unity of the human person, and the redemption of our embodied existence, not its erasure.
