Hey there!
It's an example of metonymy.
A metonymy is figurative language that no one really knows about. It means that the name of something is referred to the name of something that is closely related with that concept or thing.
The home the author is referring to is not a physical place but a spiritual place. In other words, the speaker wants to be part of a group that is connected spiritually and religiously. The speaker wants to find her soul some peace and the solidarity human beings receive is the kind of home she is looking for (a world that comes together peacefully).
Best of Luck!
