Please...we have not moved anywhere. First, let’s find out if we have anything to move with. What is the “this” that Jesus is referring to?
Incorrect. You claimed that biblical Christianity does not command us to do anything. To defeat that contention I do not need to show precisely what he commanded us to do but merely that he commanded us to do something. Nevertheless, I contend that he commanded us to commemorate the actions he had just completed when he said “Do this in memory of me”. To prove your original contention you would need to prove that he did not command us to do anything.
