Final answer:
The provided information does not directly specify which entities AGUSM works with. Churches participate in community services such as civil rights, charitable activities, and mission trips. There are numerous Protestant denominations, and some countries have a dominant state-church influencing national institutions.
Step-by-step explanation:
The entities with which AGUSM works are not specified in the provided information, making it difficult to directly answer the question 'What are two of the entities with whom AGUSM works?'. However, addressing the broader topic of religious and community organizations, we can see that churches engage in various types of community service, advancing civil rights, and providing youth activities in settings around the U.S. Some examples include Catholic Charities, Habitat for Humanity, and international mission trips.
In terms of variation within Christianity, there are numerous denominations within the Protestant church, such as Methodist and Seventh-day Adventist. This diversity in belief systems can lead to different forms of practice and worship among churches, which can be seen in the historical context of global religions. Religious organizations can sometimes operate like a state-church, where a single religious denomination is pre-eminent in a country and can significantly influence national institutions.
