Interestingly – I know you just misspoke – the translation of the actual (Biblical) readings themselves is one thing that has
not changed. It is the rest of the Mass itself that has been re-translated.
As you may know, after Vatican II the old Latin Mass was revised and a new version, the one we’re used to now, was issued. But it was issued in Latin, not English. Local bishops’ conferences were given the responsibility of translating the revised Mass into the various vernacular languages. In English, a translation was done very hastily and appeared in 1970; it is this translation that we had been using ever since then. Although the 1970 translation had some merits, it also had a lot of faults, and there had been plans ever since about the mid-1970s to revise it. Some work was done during the '80s, then some more during the '90s which culminated in a proposed 1998 missal which was not approved by the Holy See. Finally in 2001 the Vatican under John Paul II issued a document named
Liturgiam Authenticam, which called for renewed efforts to ensure that the local translations of the Mass, not just in English but in all other languages, accurately reflect the authentic liturgy of the entire Church.
It took about ten years starting from
Liturgiam Authenticam to produce a fully revised English translation from the Latin and send it through all the stages of approval and oversight. I thought I’d describe the history for you a little bit because there are a lot of people who wonder, “Out of everything the Church has on its plate, why do this
now?” The answer is, it’s a process that started in the mid-'70s and really got kicked into gear in 2001 – and it just so happens that
now is when it got finished!
