A translated excerpt from the Italian Codex Simulationista (S1.s3.2)
Transubsimulation is defined in the Simulationist faith as the point in time at which the base code that makes up/represents/is the universe in which all simulations (ourselves included) reside became/becomes real/simulated. Unlike the concept of transubstantiation in the Catholic faith, which occurs every time the wine and eucharist is made real (into the blood and body of Christ) during the Catholic mass, transubsimulation only occurs once (per level of the simulation, if such levels actually exist/are simulated). Some Simulationists have argued that the concept of time itself is only relevant in the simulation, and therefore to suggest that transubsimulation occurs at a point in time is incorrect. For these atemporal transubsimulationists the “birth” of the simulated universe occurs at no time but instead represents the first moment of (simulated) time itself. The correctness of either view may be impossible to ascertain until the coming of the Simulator(s).
Some have drawn parallels between transubsimulation and simulational submersion (the process whereby a person comes to accept the reality of the simulational nature of the universe and themselves within it). This body rejects that comparison as it seems clear to us that one occurs only at a point in time or is the beginning of time itself for the entire universe (ts), whereas the other is a process which occurs over time and happens on an individual not universal level (ss)…….
