And here is the part that matters most for using it safely: it is almost always spoken from inside a faith, looking out. A religious community calls other people unbelievers; people rarely put that name on themselves. Because of that, the word can carry judgement — sometimes gentle, sometimes not. In older writing and in translations of religious texts it can sound quite hard, marking a line between us and them.

And here is the part that matters most for using it safely而這是安全使用這個字最重要的一點 it is almost always spoken from inside a faith, looking out它幾乎都是從信仰內部往外看，講出來的話。A religious community calls other people unbelievers宗教群體會把別人稱作unbelievers people rarely put that name on themselves很少人會自己這樣稱呼自己。Because of that, the word can carry judgement也因此，這個字可能帶著評價 sometimes gentle, sometimes not有時溫和，有時不然。In older writing and in translations of religious texts it can sound quite hard在較舊的文章和宗教文本翻譯裡，語氣可能相當重 marking a line between us and them劃出一條'我們'和'他們'之間的界線。

So if you are describing someone who has no religion, the safe, neutral words are 'atheist', 'non-religious', or 'not a believer'. Save 'unbeliever' for when you are reporting how a religious group talks, or writing about religion.

You will also meet it in a wider, joking way in ordinary English, which is worth knowing so it does not confuse you: someone who is passionate about a football team, a band, or a phone brand may call the people who do not share their enthusiasm unbelievers. That use is playful and always borrowing the religious flavour on purpose.
