I was baptised in Blackheath in the Old Rite Latin Mass.
It was during a time of growing upheaval in the Catholic Church - when the Second Vatican Council was underway, and the conciliar eruption was simmering like a volcano, waiting to explode onto the world - the eruption began in earnest after the close of the Council on 8th December 1965, 3 years after it started. The church had been well and truly infiltrated by freemasons right up to the highest levels of the church, including pope John 23rd. Freemasonry was always banned in the Church - under pain of excommunication. The nuns at my mother's school in Shaftesbury told the girls that the freemasons get the devil out of the box. That's very apt.
One of the disastrous results of this heinous council was the change to the ancient Mass, from Latin to the vernacular. This was under the guise of making the mass more attractive to Protestants and other denominations. Of course, during the Reformation - the Church of England changed the Latin mass to the vernacular, and the modern mass is akin to the protestant church service. The Latin Mass never went away during the Reformation, it went underground and brave priests were hunted down and martyred if they were caught saying the ancient Mass. That's why there are priest holes in country houses.
Back to the modern council - the Latin Mass went from Latin to the vernacular in around 1969.
My mother describes the changes as -
'One Sunday we had Latin Mass, and the following Sunday we had guitars".
A handful of brave cardinals did not accept the New Mass - and one of them was the late Archbishop Lefebvre. He refused the say the new mass, as he said it was protestant, and probably invalid. He started the Society of St Pius X, which was to preserve the ancient rite of the Mass.
Around about the same time as the modern 'mass' was in force, pope Paul 6th decided to change the episcopal rite of ordination - and this, according to Archbishop Lefebvre, made the rite at best - dubious. The implications were massive, because, if the newly ordained bishop was only dubiously ordained, it rendered the priests he was ordaining as dubious too! Just think about that - over many decades of using the new rite, eventually all priests would only be dubiously ordained. If their ordinations are invalid, it invalidates their sacraments! How terrible is that! The modern day Confirmation rite is also dubious and it's a good idea to get a conditional confirmation by a valid bishop.
God obviously used Archbishop Lefebvre to preserve the ancient Mass, and not only that - he ordained 4 bishops in the ancient rite, so that they could validly ordain new priests. The brave Archbishop was excommunicated by pope John-Paul 2.
Out of the SSPX, came the Sedevacantist movement, which holds that all the popes since John 23rd are invalid, as is the Second Vatican Council.
I studied Vatican 2 at Maryvale Institute in Birmingham in the early 2000s. What stuck me was the duplicitous language of the documents - and the slippery language used. It was Cardinal Kasper who said in an interview, that the wording of the council documents was deliberately done, to make the documents ambiguous! That my dear people should make you flee from the modern catholic church as fast as possible. Compare the slippery language to the Vatican 1 council of 1870, and you see that the 1870 documents are black and white - no ambiguity anywhere!
If you want the true valid Mass you need to do your homework! Find a Latin Mass - but more importantly, find out whether the priest was ordained in the new or ancient rite. Many so called conservative priests say the old Latin Mass, but their ordinations are dubious and therefore you might not be attending a valid Mass!
IF YOU GENUINELY LOVE THE TRUE CATHOLIC FAITH YOU REALLY NEED TO WAKE UP TO THE DISASTROUS VATICAN 2 AND ONLY ATTEND A VALID LATIN MASS.
If you are a priest reading this - ask yourself - was I ordained properly or not? if not - please get conditionally ordained asap.
