I recently learned how to offer Mass in the Extraordinary Form. Often referred to as the Latin Mass, it uses the Missal of 1962, which in the period after the Second Vatican Council was on the verge of extinction. Then, in 2007, Pope Benedict XVI issued Summorum Pontificum, an apostolic letter granting permission to all priests of the Latin Rite to say the Mass in the older form. He referred to it as the Extraordinary Form and the newer form as the Ordinary Form. Both, he said clearly, are part of the same Rite.
