John Chrysostom's sermons contain numerous discussions on the topic of property rights and almsgiving. The relevance of the two has not yet been adequately addressed in previous studies. This article reinvestigates almsgiving in light of John Chrysostom's view of property rights. He argues that all things were created to be shared in common, and that private ownership of property, as a by-product of original sin, did not exist at the beginning of creation, but emerged after the fall of man. Thus, human beings do not have ownership of property, but only the right to use it. In the secular world, those who possess more wealth are mere "stewards" of that wealth, and apart from meeting their own basic needs, they are expected to share and use the property under their management to help others. Another aspect is the consideration of the limited property rights enjoyed by human beings, so almsgiving is therefore necessary, that is, those who possess property need to fulfill this obligation. In practice, however, he considered that it would be sufficient for the property holder to use only a portion of his property to fulfill one's almsgiving obligation.
