Short Answer: Yes.
Long Answer: 
    The Gods and Goddesses refer to this as the Olympian faith, and team-members have come to accept this is so, though it is difficult to imagine that something so enjoyable could be called a religion. But that religion is so often presented in the modern world as fun-free is no fault of theirs.

So what is it to be religious? 
    For many people religion is the reassurance: 'Ask and you shall be given.' However, team members understand the Olympian faith is: 'Be responsible and you shall be respected.' If you ask for something who would you call upon? To ask one Goddesses or God to alter your life means they must interfere in the plans of others.
    Ask and you may get what you wish for or you may not. Some Gods and Goddesses will give you the gift that you may call upon them. 

Team-members agree the relationship between humans and the Gods and Goddess is one of mutual respect. Humans respect them for their work of creation and maintenance of life, of which we are part. They respect us for the way we conduct our lives.
    Not so much: 'ask and you shall be given', but 'don't ask and you shall be respected.' Remember they can see the bigger picture, and getting what you think you want may not always be for the best at that time, but they can and do help an individual in many different ways. In short they wish to be honoured for their work, not for what they will give you.

What this faith requires of anyone is to remember the different Gods and Goddesses on their celebration days. Celebrate with them, or remember them in some simple way.

The Gods and Goddesses work hard, believe mortals should do the same, though bear in mind - as you will find included in the Unknown Gods and Goddesses series pages - there is a God who's job description it is to be lazy. Generally then, they think humankind is best when happy and working at something worthwhile. Those who bring harm and evil to others will spend some time with one of the deities when their life is over. Hades' Assessors, the Cyclops, the Erinyes and any of the Titans are best avoided. And of course regular evil-doers face the Devourer for termination.
    The Olympians enjoy themselves, not at our expense, but celebrate all of creation. They expect us to do the same as best we can.
