• Ethics of knowledge: The moral principles that guide us in the pursuit and dissemination of knowledge.
• Religious tolerance: Acceptance of different religious beliefs without prejudice.
• Christian ecumenism: Effort by different Christian churches to promote mutual understanding and good relations.
• Global ethic of justice: A universal standard of fairness and equity applicable to all religions and cultures.

Our ethical responsibility to learn about different religions could contribute to a more tolerant and understanding world. However, this idea, based on Christian ecumenism, might not be universally applicable due to its specific context and history.

It's often assumed that a secular approach to studying various religions can foster tolerance and intercultural understanding. Is this true? Do we get more tolerant as we learn about religious diversity? Or do we need to learn about the belief systems themselves?

Example: Think of the difference between a Biology and a Music class. In Biology, you learn about different species (like religions), and in Music, you learn to appreciate various forms of music by understanding their unique attributes (like understanding belief systems).
