<P> A further distancing between the concepts of `` Tridentine Mass '' and `` Latin Mass '' was brought about by the 1964 Instruction on implementing the Constitution on Sacred Liturgy of the Second Vatican Council , which laid down that `` normally the epistle and gospel from the Mass of the day shall be read in the vernacular '' . Episcopal conferences were to decide , with the consent of the Holy See , what other parts , if any , of the Mass were to be celebrated in the vernacular . Permissions were thus granted from 1967 onwards to celebrate most of the Tridentine Mass in vernacular languages , including the Canon . </P>
when did they stop saying mass in latin
from 1967 onwards
