What do you call a person or community that grants refuge?

Legal texts typically use the term harborer (harbourer, UKSE)

Consider calling the person who takes a refugee into their home a host. The place is simply termed a place of asylum, where asylum is used in the sense of the definition below. (The country can also be called a host.)

host noun 1 A person who receives or entertains other people as guests. - ODO

asylum noun 1 (also political asylum) mass noun The protection granted by a state to someone who has left their home country as a political refugee. ‘she applied for asylum and was granted refugee status’ - ODO

Here's a wikipedia entry that uses the term country of asylum in this manner:

• By country of asylum - wikipedia

Here are a couple of examples where the word host is used in this context:

• Becoming a host is an opportunity for you to show solidarity to people in need and help in a very real and practical way. - Refugees Welcome

• But there's also a lot of relief and pleasure for the host and guest. Living with refugees neutralises fear and loathing. - The Sydney Morning Herald

Here are a couple of examples where the word host is used as a verb. This is arguably a case of zero derivation, and we can call the person or place doing the hosting a host.

• Due to the incredible surge of interest in people offering their homes to host a refugee, Alyan’s List organisation has been developed in partnership with Australian Homestay Network to implement a placement program. - Australian Refugee (note: host here is used as a verb)

• Ten countries host half of world's refugees - News Grid

Given that new "sanctuary cities" are gaining new traction, this is a very timely and relevant question. While "harborer" and "host" may serve, is it time to introduce "sanctuarist" to denote someone who actively runs a sanctuary or is active in a sanctuary movement or who promotes the provision of sanctuary to those seeking it?
