A system of beliefs, practices, or social organization based on distinction between gentile and non-gentile peoples, or a state of being non-Jewish.
From gentile plus the suffix -ism, which transforms nouns into ideologies, systems of belief, or practices, as in racism or feminism.
The -ism suffix marks ideologies and systems—so gentilism describes not just a category of people but a whole worldview that divided humanity based on religious or ethnic identity, particularly in theological contexts.
