>Remember that the devil hates Latin and the sacred ancient Latin Sacraments, Rites and prayers of the Catholic Church. So you can see that it was precisely when Latin was being removed, (1965-69), that all hell broke loose. Many ask why the devil hates Latin and why it is used in Exorcisms and has power over the devil. The answer is that ecclesiastical Latin is a sacred language that was reserved only for the divine service of the Church of God, in prayer and in the Sacraments. (There is classic Roman Latin of Cicero that is also studied today. But it is significantly different for the sacred ecclesiastical Latin.)
>Our profane language is English. It is used to cuss with, to curse with, gossip with, to lie with, to deceive with, to corrupt souls with, along with all the other common ways it is used to communicate with. On the other hand, ecclesiastical Latin is only used for holy things, and is a dead language that does not change and has been reserved for centuries just for prayer, (especially the Latin Mass). For this reason, the devil hates it.
