Why is everyone talking about this? Well there’s a lot at stake here. Much of early Christian theological debate is taken up with the issue of how Jesus is both a god and a human being. Early on there were some early Christians who thought that Jesus only “seemed” to have a human body but in reality was a god. You can see why Christians who held this position thought Jesus never went to the bathroom. This position, which is known as Doceticism, would come to be rejected as heresy, but those who wanted to argue that Jesus was truly human have to explain how the combination of humanity and divinity works. While they are doing that they are also trying to avoid the idea that the divinity in Jesus is somehow defiled by or corrupted by all the disgusting aspects of human bodies. Excrement, in particular, was just the kind of disgusting thing that people wanted to avoid.
