What I want to ask though is, how does one get pass the Latin prayers or chants if they cannot understand them?
Most devout Catholics utilize a Roman Missal, which contains all of of the prayers of the Mass in both Latin and English, side by side. Over time, you start to gain more understanding of the Latin language just by sheer immersion in the liturgy.
Does one diligently look up them up beforehand or even learn the Latin language?
The Roman Missal gives detailed instructions for the canon of the Mass, as well as the variable readings for the Mass. You do not need to understand Latin to follow along with the priest during the Mass as long as you have the English translation next to the Latin. Technically, you could pray internally the entire Mass in English as the priest reads the Latin aloud.
Many of the words in Latin have a close English equivalent as well, which makes certain Latin words easier to understand.
Could things such as a small placards in the pews that translate the prayers from Latin to English or whatever local language help draw people in?
These translation booklets are already readily available in most parishes that celebrate the traditional Latin Mass.
What is the allure of a Mass you cannot understand?
In all seriousness, for those of us who are attached to the traditional Latin Mass, it is truly hard to describe the attraction to this particular form of the Mass. The Latin Mass is truly “experiential” in nature, and a beckoning back to traditional modes of prayer, liturgy, and spirituality.
There is also a sense - especially in modern Western culture - that our secular culture needs the traditional Latin Mass, that we have somehow lost many of the older values that were so esteemed in past generations.
The traditional Latin Mass is the Mass of our ancestors going back many centuries. Many of us knew instinctively for many years that “something was missing” personally in our spiritual experience, and the traditional Latin Mass filled that void,
The traditional Latin Mass brings many spiritual blessings beyond number and explanation. Getting past the language issue of the utilization of Latin was, in all objectivity, a relatively minor issue.
Most traditionalists are very committed to the traditional Latin Mass for any number of reasons. I would venture that the main reason is that the culture of the traditional Latin Mass aligns with core values. The Mass is also very beautiful and reverent. The liturgy is also highly mechanized, allowing little room for the priest to “improvise”.
