If there is no "correct" defintion, then logically I could say the only way to be saved is to kill someone. Now since there is no standard, you can't say I'm wrong. The only way I can be wrong is if there is a correct defintion.
I know. You wouldn't be wrong. But if that's how you defined 'salvation', then when you use that word, you would in a way be using a different word than others who use the word 'salvation'. Though there is no "correct" definition for a word, there is a current lexical definition (the way which the word is usually used in everyday speech), which one could say is the "standard". For that time.
Anyway, using a new definition that no one knows would be utterly useless for communication purposes.
