In it's earliest iteration, what is now called Vita was conceived of as a religion devoted to Gaia in a blog post pasted to Linked-in titled Gaia: a New Religion Devoted to a Sustainability. In Australia a religion is defined as a belief in a supernatural and the canons of conduct that give effect to the belief. After sharing this idea with many people it was found that religious people weren't looking for a new religion, and non-religious people weren't looking for a religion, in the first place. So, we were in the process of inventing something that people didn't want. However, we also found that people were interested in spiritual philosophy relating to nature. So, we continued developing the concept of Vita with a focus on the spiritual philosophy and downplaying the canons of conduct and the supernatural aspects
When Vita was formed as an institution and registered as a charity, we needed to allocate a charity sub-type or sub-types. As there was no charity sub-type called Advancing Spiritual Philosophy of Nature, we had to choose from what was available on the list and the best fit seemed to be a hybrid between Advancing Religion, Advancing Natural Environment, and Advancing Education. In response the charity commission approved our submission subject to us dropping the Advancing Natural Environment and Advancing Education charity sub-types. As a result, the Vita institution is technically a registered religious institution although Vita Sapien is framed as a Life Philosophy in our outward communications.
Vita Sapien organization contains a religion in that it ascribes a supernatural - Vitae-planeta - and canons of conduct which are referred to as Practices.
Ultimately, the question is framed by one's definition of religion. The Australian government has one view on the matter, and the video above shows other views. So, ultimately the answer to the question is subjective: do you believe that Vita is a religion?
And if so, does it matter?
