You are right. The direct etymological connection to the phrase used in the Vulgate (4th century Latin translation of the bible) I was trying to make doesn't exist. At most a weak allusion. The latin word "fiat" ("let it be done") has different specific uses in English, I wasn't aware of, one of which is generally an arbitrary or authoritative command or order to do something; an effectual decree.[0]; which fits the bill much better (: [0]https://en.m.wiktionary.org/wiki/fiat#English https://en.m.wiktionary.org/wiki/fiat#English
