I started to answer & was going to say 'no, definitely not, faith is a way to believe in something without evidence & even despite evidence to the contrary.' Then I stopped my initial reaction & went & looked up the word on dictionary.com.
This is some of what it came up with:
1. confidence or trust in a person or thing: faith in another's ability.
2. belief that is not based on proof: He had faith that the hypothesis would be substantiated by fact.
3. belief in God or in the doctrines or teachings of religion: the firm faith of the Pilgrims.
4. belief in anything, as a code of ethics, standards of merit, etc.: to be of the same faith with someone concerning honesty.
5. a system of religious belief: the Christian faith; the Jewish faith.
6. the obligation of loyalty or fidelity to a person, promise, engagement, etc.: Failure to appear would be breaking faith.
7. the observance of this obligation; fidelity to one's promise, oath, allegiance, etc.: He was the only one who proved his faith during our recent troubles.
8. Christian Theology. the trust in God and in His promises as made through Christ and the Scriptures by which humans are justified or saved.
—Idiom9. in faith, in truth; indeed: In faith, he is a fine lad.
This made me realise how I have come to view the word faith in purley one or two ways of late.......
By definition 1, yes, kind of, as that kind of confidence can be based on knowing humans in general and how they behave and even more by knowing a specific person and how they are based on past actions. I like the words 'confidence or trust' better than faith though.
By definition 2, abosolutely not - this was the definition that provoked my original response.
Similarly with 3, 5 & 8. I have no 'faith' (or confidence or trust) in these 'Faiths'
(ok the word is starting to look really weird now.......)
4 & 9 not really sure these apply - they are less active uses of the word.
6 & 7.....hmmm...that is opening an entirely different can of worms based on whether people should make promises, if it is ok to break these under some circumstances.....I think I would like to say yes to this one...but maybe am a little too aware that promises of this nature are easy to make & often are made with out acknowledging how life can throw all kinds of things at you. I guess I have faith (by definition one) that there are some people out there that are capable of this. Does it make them happy ? Is it the right thing?...who knows.....depends very much on the person and the size of the obligation / promise.
Oh.....you said you were in a lighter mood when you asked this....I guess I was not listening... :)
