*Sigh* On Faith Again

Why should anyone who rejects Christianity adopt the Christian definition of faith? We think it's not what Christian believers do in practice, and it does nothing to actually define the word faith because other religious faiths should be included when defining faith, otherwise Christians have a private language game unrelated to how anyone else uses the word. Words are about concepts. If the Christian wants to maintain such a concept and call it faith that is their privilege. But it's delusional.
