Regardless if this is a joke or not, this is not acceptable, you can't put religious things in the code of conduct. Even if it is a joke, it is still awful and I wish that it gets removed quickly.
> you can't put religious things in the code of conduct.
Why not? Isn't the whole point of a code-of-conduct to describe the ethical values of a community? And isn't all ethics a kind of religion, even if it does not always make explicit mention of deity? From that point of view, every code-of-conduct is a credo, by definition.
Suppose I were to go in and edit St. Benedict's rules to omit all reference to "God" and "Christ", leaving behind such things as "do not steal", "do not nurse a grudge", "do not return evil for evil", and so forth. Would the document be acceptable to you then? If not, then what exactly are the ground rules for codes of conduct? And who makes those rules? Is there a code-of-conduct for codes of conduct?
If you answer "Yes" to the previous, then are you suggesting that you and/or I are somehow wiser than Benedict of Nursia, such that we are able to edit and improve upon his work?
well yes you could if you put it like that, my main point is that in that case you would have to make sure the community as a whole (all the main devs) share that point of view.
Not OP, but 1500 years of hindsight can give knowledge that could make up for any deficiency in wisdom. Furthermore the rules were written for those who were already professing belief in the christian deity.
