In general, religious traditions stress our duty to god, or to some universal ethical principle. Our duties to one another derive from these. The religious concept of rights is primarily derived from our relationship to this divinity or principle and the implication it has on our other relationships. This correspondence between rights and duties is critical to any further understanding of justice. But, for justice to be practiced; rights and duties cannot remain formal abstraction. They must be grounded in a community (common unity) bound together by a sense of common union (communion). Even as a personal virtue, this solidarity is essential to the practice and understanding of justice. Which one of the following is the crux of this passage?

The crux of the passage is the interconnectedness of rights and duties as fundamental to the concept and practice of justice. Analysis of options: A) Our duties to one another derive from our religious traditions. This statement is mentioned in the passage as an initial premise ("Our duties to one another derive from these [duty to god, or to some universal ethical principle]"). However, it is a starting point, not the main argument or the "crux" of the entire passage, which delves deeper into the relationship between rights and duties and justice. B) Having relationship to the divine principle is a great virtue. The passage mentions the relationship to divinity as a source for rights and duties, but it does not explicitly state or emphasize it as a "great virtue." This is a misinterpretation and not the central theme. C) Balance between and duties is crucial to the delivery of justice in a society. This is the correct answer. The passage explicitly states, "This correspondence between rights and duties is critical to any further understanding of justice." It then elaborates that for justice to be practiced, these rights and duties "must be grounded in a community" and that "solidarity is essential to the practice and understanding of justice." The idea of "correspondence" implies a necessary balance or interrelation, making this statement the most accurate summary of the passage's central argument. D) Religious concept of rights is primarily derived from our relationship to god. Similar to option A, this is a specific detail mentioned early in the passage regarding the origin of rights. While true according to the passage, it is a foundational point, not the overarching "crux" which is about the implications of this derivation for justice through the balance of rights and duties.
