No. Vatican II's Sacrosanctum Concilium §36 states: 'Particular law remaining in force, the use of the Latin language is to be preserved in the Latin rites.' Section 54 further instructs that 'the faithful may also be able to say or to sing together in Latin those parts of the Ordinary of the Mass which pertain to them.'
