A non-Christian is a person who does not identify as Christian or follows another faith. It can also describe beliefs, practices, or cultures not rooted in Christianity. Use it neutrally to distinguish religious identity or context, not to judge.
But for those who lived in non-Christian lands, it was decreed that the work of conversion was an imperative. It is, in a sense, a pity that this work will always be remembered for its association either with conquest, with religious fratricide or with imperialism. Christopher Hitchens
There is no way to use non-Christian language and logic to arrive at Christian utterances, conclusions, and behavior. Greg L. Bahnsen
