Peter, the denier, the dissembler, the man who means well, the man who cocks up time after time. The man who sometimes gets a bit above himself and has to be given a slap. Homer Simpson in fact. You. Me.
Cut us in two and we have humanity written all the way through us.
Cut us in two and we bleed. Some of the things that help us to stop bleeding are platelets. These are not blood cells, but are broken-off pieces of huge cells (megakaryocytes) that lie in wait to be summoned to wherever they are needed to plug the holes in the pipes. Biological Radweld. We are broken off bits of the Divine. To be sure, we have other things in us too that are maybe not so Divine, but we are all sons and daughters of the Divine.
Platelets bind together when they recognize damaged blood vessels. They aid blood clotting to stop blood seeping out of damaged vessels. Blood is life force, so pushing this silly simile a bit further, we stop the life force seeping out by plugging bleeding hearts, easing burdens, bringing delight. Blood brings iron, oxygen and nutrients. Blood disposes of waste products.
On this rock. Not the rock of perfection, superiority, excellence and aloofness, but the rock of humanity with its tendency to wander off like a supermarket trolley, and its ability to act as plugger of holes, mender of fences and bringer of jollity.
O admirabile commercium.

aloofness – my neighbours new wife recently met a mutual acquaintance of ours (yours and mine). She described him as “aloof”. He proceeded to inform her as to what parish she lived in, contrary to what she had said, and contrary to reality as well – superiority. One guess allowed 😉
I am in awe of such people: experts in everything. I suppose a special part of heaven will be reserved for them, just to the side of the throne, in a chamber with its own entrance.
