Because I follow the theological teachings of Emanuel Swedenborg, this tidbit fascinates me. Swedenborg claimed that the natural/physical realm was a theater for spiritual processes to play out as physical metaphors and allegories. He called this connection and communication between spiritual and physical qualities the science of correspondences.
(I once had a Swedenborgian minister ask me if Swedenborg actually referred to this symbolic language as a science. And yes, he most certainly did!)
Everything that happens in the physical world corresponds to some ontological reality in the non-spatial and non-temporal actions of the spiritual world. Therefore, the trend towards increased anal sex could tell us a lot about the spiritual trajectory of the human species.
Swedenborg wrote brilliantly about the different sexual organs of both men and women in a scientific work (Organs Of Generation) and later stated, in his theological writings, that the conjunction of a man’s sperm with a woman’s ovum was symbolic of God’s Truth and Love joining together to form all the things of creation. (In men and women, the sexual act also symbolizes the deeper operation and sacred process of spiritual transformation.)
So I have been pulling my hair out to find the noble symbolism behind anal sex. Could someone who understands spiritual symbolism better than I explain the profound lesson of divine order being represented by such a practice?
Otherwise, Swedenborg’s Bible imagery does not rise to the level of a universal teaching.
