If he were a muslim and added some Sufi-inspired rules I don't think there would have been more complaints than the Rule of St. Benedict gave rise to. If he cited those parts of islamic scripture which call for conquest by the sword there would - hopefully - have been uproar as those espouse an exclusive and oppressive ideology, just like there would have been more of an uproar if the sqlite project cited the more vile parts of, say, Deuteronomium.

I see this 'code of conduct' as a literary form of pro-biotics [1], there to protect against invasion by harmful non-transcendental religions like intersectionality which have the capacity to sow discord and tear communities apart into warring factions. Even though I do not believe in transcendental gods I have no problems accepting the Rule as I see it for what it is, an abstraction of monastic life written to the benefit of medieval monks. I am under no vow of obedience or poverty and I am rarely in a situation where I have to bury the dead so I know I can skip those parts which are not applicable. In truth, I realise I can skip just about everything except the bit which tells me to treat others as I'd like to be treated myself.
