許多學者常常將墨家和基督宗教的普遍愛人主張相提並論，甚至認為二者都提倡無條件愛人。本文認為，二者主張的普遍愛人觀念以其各自的正義底線——「不可虧害人」和「愛上帝」作為先決條件，而兩種正義底線的實質差異從根本上決定了二者普遍愛人觀念各自呈現出人本主義和神本主義的不同特質。

Scholars often accentuate the affinity and even identity between the Mohist and Christian universal love. More than that, many of them even believe that both argue for an absolutely unconditional love. This paper argues however, that both propositions of universal love are not absolutely unconditional, as Mohism and Christianity propose “not harming others” and “the love of God” respectively as prerequisite of universal love. Upholding these two different prerequisites as the fundamental principle of justice entails two essentially different orientations of their universal love: humanism for Mohism and theism for Christianity.
