I just want to add one thing here from my personal experience. I spent seven years as a missionary in Latin America and three more as a university dean.
Hispanics are very protective of their heritage and their language. Though most of them really admire and love the United States, they have been abused so much, first by Spain and later by their own leaders, that they have developed a culture of suspicion.
If you take away the Spanish language mass and replace it with the TLM, the parish runs the risk of losing these people, because it can be misunderstood as discrimination. They will wonder why take away the ONE Spanish language mass and leave three English language masses.
In addition, unfortunately, whether we like it or not, their history with the Catholic Church is very different from our own. They were colonized by Catholics. If you visit any city you will find beautiful cathedrals and basilicas built along Spanish and Moorish architecture. Some are spectacular, but they are empty on Sunday.
The smaller and simpler churches draw the large crowds. There is a historical reason. These spectacular churches were built by the crown or with the support of the very wealthy. But it was the very wealthy who stole from the working classes and have oppressed them to this day.
It is only natural that people make associations, even if they are incorrect ones. Most Hispanics see the very elaborate churches and the pomp and circumstance as a sign of wealth and power. This frightens them. This is one of the attractions that the Protestant churches present to them, the simplicity.
To keep these people within the Catholic Church we must make careful and prudent pastoral decisions that take into consideration their culture and their experience. If they can feel the presence of Christ in the simplicity of the NO in their language, why rock the boat? I don’t believe this is what the Motu Propio intends.
Observe that John Paul II brought back many Latin American Catholics to the Church with his simplicity and his openness to their style of reverence and adoration. He put more than two decades of work to bring Latin America back. It was falling into the hands of the Protestants and of the Marxist Liberation Theologians.
I don’t believe that Benedict would want to undo all those years of work.
So taking away a Spanish language mass when you have three or four English language masses to choose from, would not be such a practical idea. It would create suspicion where no harm is meant; but that’s human nature.
I hope this makes sense.
