Consider our passage today in Leviticus. He who is holy calls his people to be holy, like Father like child, a set apartness of and for God. What follows is a less succinct almost lyrical expansion of the Ten Commandments, an elaboration on what it means to love God and examples of what it looks like to love our neighbor. For example, it may surprise us to find that despite the thousands of years that separate us from ancient Israel, how Israel is commanded to love their neighbor is remarkably relevant for us today. So, if I too may summarize, loving our neighbor means loving generously, honestly, equitably, justly, and reasonably.
The basic definition of stealing is taking “(another person’s property) without permission or legal right and without intending to return it.” What someone owns is theirs, and if you take it you are stealing. But stealing is not necessarily limited to property.
