There is no single, correct mode of embodiment. For those who regard themselves as part of the body of Jesus, part of the family that grows from Jesus’s body, that one body is really many bodies, complicated bodies, with hands, blood, some foreskins, and a whole lot of multi-colored flesh.
The promise that Abraham will become a great nation is connected with the circumcision of his foreskin, forging a connection between sex and politics. This connection has controversial and unsettling resonances in a liberal society that would often separate the two.
