The revised edition of the Roman Missal that was promulgated by Pope Paul VI in 1969 presented two forms of the Order of Mass: Ordo Missae cum populo and Ordo Missae sine populo.
The 1970 General Instruction of the Roman Missal dealt with the first of these forms of celebrating Mass under the numbers 77-152,[REF] and with the second under the numbers 209-231 [REF].
