Some differences lie in program philosophies. Many organizations that place or take volunteers have distinct approaches to service, often integrating their understandings of service with values or “pillars” that present their vision of how a volunteer (or a person generally) should live.[15] For instance, the Jesuit Volunteer Corps identifies its “values” as social justice, community, spirituality, and simple living.[16] An integrated approach to service means living out these values and includes specific actions for the volunteers that speak to them and build on them.[15]
