when did catholic mass change from latin to english
Latin Mass 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.[3] Permissions were thus granted from 1967 onwards to celebrate most of the Tridentine Mass in vernacular languages, including the Canon.
