Digital technology is changing the world. In response to global challenges, diverse grassroots faith-based organisations, indigenous or otherwise, are using digital technologies to activate for justice.

Some of these organisations describe themselves as indigenous. Others find terms like grassroots more helpful. Academic analysis of these local digital activisms provides ways to learn with and from online theologies that are immediate, provisional and contextual.
