Campus Ministry

In Harry Potter and the Order of the Phoenix, when Harry and his friends go into the department of mysteries, where is everyone? Why are there no ministry workers?

Sorry if thins is a stupid question.

Thanks

I think there may be two reasons;

1 – It was night, so folks were no longer at work. In Deathly Hallows, we see/read that when Ron, Hermione & Harry transform into Ministry employees using Poly Juice potion to get in, it is very busy with a lot of people arriving for work, likely meaning Ministry employees worked "regular" 9 – 5 hours, leaving the Ministry nearly empty. Obviously with the exception of Aurors, but I doubt an Aurors job would see them spending a lot of time at the office, and especially at night.

2 – Voldemort and his Death Eaters may have already begun using the Imperius curse to manipulate junior Ministry employees, so as to keep them away. Folks were still in denial that Voldemort had returned and he would likely have embraced the idea that his return was false, so violence would not have been used to clear the ministry, leaving the Imperius curse as an option.

I am a member of a church in Florida that is a strong advocate for missions and serving, however the vast majority of service opportunities are either in our local city, or in other countries. I am just wondering if anyone out there is a part of/knows about any good Christian ministries that intentionally serve people throughout the US.
I’m most interested in some kind of organization that coordinates trips or outreaches across the whole country. Habitat for Humanity is one example, but I’m interested in discovering more like this.
