doing unto others

The Oath is pretty simple. You can swear it amid torchlight if you like, or after a day of fasting, and the rest - some do it after debauchery - but you can also just say it:

Henceforth I swear all my will and resources to the good of all beings who have taken this oath.

This Oath is independently discovered and propagated amongst numerous worlds. If arriving roughly contemporaneously with the advent of scientific thought, the world has a 62% of becoming a post-scarcity utopia within five sapient generations. If invented and spread within an agrarian civilization, with no simultaneous invention of scientific thought, the Oath is 88% likely to be incorporated into existing patriarchal and tributary power structures within as many generations. 

On REDACTED, four out of five conditions for the emergence of scientific thought are present - so it's a toss-up on that front - and the Oath is in its early, revolutionary stages. It is rapidly accumulating heresies. These include:

• implicitarianism, the notion that the good of humanoid nature - or, perhaps, reincarnation from infinite previous lives, at least one of which must have taken the Oath - means everyone has already taken it, therefore everyone is always already obliged to the good of everyone,
• explicitarianism, the notion that the Oath's remit only extends to those who take it in the same langauge or with precisely the same ideas in mind, which has led to (1) spurious justifications for cultural chauvinism (2) miniature groupuscules who are sworn only to the good of each other,
• the Administration of the Oath, a bureaucratic structure which, by virtue of claims of expertise, regards itself as the only competent party to administer the resources and will pledged by all Oathtakers to each other
• the Cult of the Ancient Saints, which regards that since the Oath can be easily discovered, ancient powerful entities must have taken the oath, and are looking out for Oathtakers even now (it is figured that fairly traditional worship and offering is the best way to promote the good of these ancient saints in turn, and especially to let them know that you are a proper Oathtaker who they should consider as in the circle)
• the Good Sisters and Brothers of Poor Queen Ntalchy, a move towards the mutation towards tributary and patriarchal power structures already known; since Queen Ntalchy is a good queen and the laws of the Empire of Glai are good laws, naturally Oathakers should uphold her and them, especially as she is working so hard to bring the benefits of her empire to sundry benighted folk,
• the Cenobites of Exactitude, monastic communes founded by Oathtakers who regard the Oath as only extending to those who have fully kept it - some of which have come to be supported in a kind of quid pro quo with Queen Ntalchy, 
• Latitudinarianists, those who reject the exactitudinist line completely, and go about begging what they are owed from their cosworn (what they really offer, of course, is a chance for others to practice the Oath, which is more valuable still,) 
• hyperexplicitarianists, who conclude egoism (various splits frequently end with each side declaring the other secret hyperexplicitarians)

...alongside the various forces of the old order who, unlike Poor Queen Ntalchy, haven't yet decided on a if-you-can't-beat-em-join-em approach, and are going with the traditional approach of "slaughter the weird new leveling religion."
