Some explanations here.
The Mohism is one of (if not the only one of) the schools which emphasized supernatural importance.
They preach an "universal love" as their central ideal, as well as pacifism, equality. If you want Christianity with a more modern/New testament favor, this is the closet one you can get, not even Buddhism.
They were also distinctive for their organizational structure. While other schools rely on few leading scholars to spread their ideas (often through persuading the policy makers), the Mohists act more like a (secret) society.
Members come from all walks of life, even the lower caste (Zhou was still a feudal society) can join. It is a strict and formal organization, and it's practicers are famous for their abidance to the ideals, abstinence lifestyle and bravery, which I find similarities mirroring the western monastic/knight orders.
Plus the fact that they have a strong focus on studying science, technologies, maths and ENGINEERING (which are rare among other schools), you can as well paint them as the ancient Chinese illuminati. They are a secret society after all.
