Faith: (1a) belief and trust in and loyalty to God; (1b) belief in the traditional doctrines of a religion; (2) firm belief in something for which there is no proof.
From my point of view, the first and the second definition is fundamentally different. The first definition is just a shorthand for a statement. I did not learn much except what it stands for.
Sure enough, the second meaning is also a shorthand for something, but compared to (1), it reveals a lot more. In a sense, the first definition may be likened to an acronym.
Are there linguistic terms to better articulate what I am trying to say?
