I would suggest you can't reasonably conclude that should a god go on public record, listening to its principles of morality must be a moral act. Quite honestly, there is at least one God I am aware of and I'm sure you are too which is on public record, and quite frankly, its moral standards are deplorable.Quote from kidPWRtrader:
Would you also be the last person to say if something is religious, it is moral? Would you say some things that are religious are not moral; and some things that are moral not religious? --> Yes
If there was(is) a G(g)od and he went on public record enumerating his/her/its principles of morality, then we could accurately conclude that to listen to G(g)od is to be moral. This is just not the case. G(g)od has many spokespeople, each of whom have different interpretations of his/her/its will.
Here are simple (but probably impractical) rules for "moral rightness":
1) Define what is "good", keeping in mind that being "good: will then be synonymous with "moral"
2) Assess an act based on obedience to the chosen definition
I'm largely utilitarian in my definition of "good". So, if posed with an issue that creates a moral dilemma, I might ask, "What will do the most amount of good for the most amount of life (notice I don't necessary say human life) in the long term?"
I'm in the that's-useful-but-not-entirely-true camp. This means that I think many before me and here today have excellent ideas that deserve recognition, contemplation, and inorporation (into my own life). For instance, I think Albert Schwitzer has a good understanding of morality and ethics. Yet, I don't entirely agree with everything he thought. And that's true with just about every idea and every person I've read about.
There are common values that most of us (except for the most psychologically ill among us) could agree to. The "golden rule" is a good example for this. Stealing and killing is bad, is another. But, the ultimate "good" is just too vague of a concept for most people and thus is likely to get an infinite amount of answers.
With respect, my question to you is much more straightforward than your answer suggests.
Is it moral (more moral) to do something right for the sake of it being morally right.
Is it moral (less moral) to do something because you have been told it is right via a god for instance, even though it very well may not be morally right.
Without needing to enter into semantics of morality, my argument is the former must always be more moral.
