Is Rome the Holy Land? No, the Holy Land is centered around Jerusalem. Jesus came for the “lost sheep of Israel.” It wasn’t until those invited to the banquet refused to show up that salvation was offered to everyone else— the blind and the crippled and the lame. We, since we’re not genetically of the House of Israel, are Gentiles. And the preaching to the Gentiles didn’t start until after the death of Jesus.
We don’t really call ourselves Roman Catholic, except for casually. It started out as a perjorative way to distinguish those who follow the church headed by the Pope in Rome, rather than being Anglicans, or Lutherans, or Calvinists, or others. (ie, “Papists”, “Popish Catholics”, “Romish Catholics”, etc.) But if you look at things like the Creed, it’s the One, Holy, Catholic, and Apostolic Church, not the One, Holy, Roman Catholic, and Apostolic Church. etc.
We used Latin because it was the international language commonly understood by much of the Known World for 2,000 years. It and Greek were the two major languages of commerce and international politics. Even after the fall of the Empire, Latin continued to be the language of religion, science, and intellectuals. So if someone from the Balkans wanted to communicate with someone from the Iberian Peninsula, would it make sense to hope that each knew the other’s local dialect, or would it make sense to presume that each knew Latin?
Over the last 200 years or so, scholars stopped writing their philosophy and science in Latin, and moved to the vernacular— French, German, English, and so on. And as religion moved into the vernacular post-Vatican II, Latin stopped being a staple of a good high school education, in favor of electives like Spanish or French. Latin and Greek are still a solid thing to study if you want to be a Classicist-- because there’s more stuff written in Latin than you could ever translate in a lifetime-- but we no longer rely on it as a common language.
“A man gave a great dinner to which he invited many.
When the time for the dinner came,
he dispatched his servant to say to those invited,
‘Come, everything is now ready.’
But one by one, they all began to excuse themselves.
The first said to him,
‘I have purchased a field and must go to examine it;
I ask you, consider me excused.’
And another said, ‘I have purchased five yoke of oxen
and am on my way to evaluate them;
I ask you, consider me excused.’
And another said, ‘I have just married a woman,
and therefore I cannot come.’
The servant went and reported this to his master.
Then the master of the house in a rage commanded his servant,
‘Go out quickly into the streets and alleys of the town
and bring in here the poor and the crippled,
the blind and the lame.’
The servant reported, ‘Sir, your orders have been carried out
and still there is room.’
The master then ordered the servant,
‘Go out to the highways and hedgerows
and make people come in that my home may be filled.
For, I tell you, none of those men who were invited will taste my dinner.’”
