Theory number 3.

The key point is that it's a factor. Emotion is not the only thing that makes you believe, but it's a high driving factor, with regards to these things.

Of course emotions are a high drvining factor. That's part of the problem. The rest of the problem being that emotions cloud our ability to determine what is truth. That's why when searching for truths, i.e. god's existence, our emotions must be cast aside to the best of our ability.

Hmm...we seem to have a problem. Emotion blinds us sometimes and makes us believe in false things (like religion). At the same time, without it driving others beliefs, we wouldn't believe in value, morality and praise.

So we need it to believe in some true things but it also blinds us to believe in false things.

Perhaps it's not that we have to cast away emotions, it's that our love of finding the truth and being honest to ourselves, has to overcome, and that would separate falsehood from truth.

So in this case, despite belief in value being emotionally driven, we can say we know it to be true, seeking to see the truth in that.

And that in the case of religion, we know it to be wrong, despite our original emotional attachment to wanting it to be true (in some cases).

It's a struggle really.
