To convey the meaning in Swahili, you would need to explain the concept. Here are some options:
* "Upinzani wa kutenganisha kanisa na serikali" - This translates to "opposition to separating the church and government."
* "Utetezi wa kanisa la serikali" - This translates to "defense of the state church."
* "Harakati za kupinga kutenganisha kanisa na serikali" - This translates to "movement against separating the church and government."
It's important to note that these translations are not exact equivalents and might require some context to fully understand the nuance of the original word.
If you're looking for a more specific Swahili term, you might need to consult with a Swahili speaker or expert in religious and political history.
