Christian is the umbrella term, otherwise we'd have to call by name every denomination when we talk about Christianity (especially the Saint Person Unionist MethoLutherBaptist Communal Congregational Churches that show up in the US when you aren't looking).

I remember telling people in my Middle School (including my grown-ass aide) that Catholicism was Christianity to their bafflement. Imagine my vindication when we got to the Reformation unit in History.
