I can't fathom why they would care how the Catholics see it fit to conduct their rites. Most liturgies are pretty boring affairs but you don't normally see Catholics commenting on that.
It's a backhanded acknowledgement the two churches are so similar. Catholicism's the West's No. 1 church so they're afraid of it. They're probably much less defensive on Orthodoxy's turf: Greece, Russia etc.
Right, a one-hour fast before receiving Communion; water's allowed. A rule the Catholic Church can and does change.
In Catholicism, if you think you've committed what is objectively a mortal sin, you have to go to confession and be absolved before receiving Communion. No mortal sin, no confession unless you want to.
I knew the deacon at the modern Mass was imitating the Torah dance but it's still contrived and silly.
The Anglicans (Anglo-catholics, that is) built beautiful neo-gothic cathedrals and churches in Ireland, hoping to attract Irish Catholics by bedazzling them with the glories of medieval Christendom. For some reason, it didn't work.
No.
Irish religious history from the 'Reformation' on is full of surprises. Some say Irish piety is cyclical; one generation's lapsed, the next pious. It's on the downswing now. Anyway, the Irish at first pretty much went along with the king's breaking with Rome mostly because the conservative clergy did a good job of hiding it so religion in the parishes was pretty much the same. The first people in Ireland to rebel against the king's break with Rome were the ethnic
English living around Dublin. So arguably you can credit them for the identity 'Irish Catholic'. (So much for Irish Catholics hating the English, which isn't universally true.) The then-state church didn't really become noticeably Protestant until later in the 1500s, when the Irish caught on that it wasn't Catholic anymore and said no. The ethnic English upper class there remained Catholic for a few generations. But eventually the Anglican Church there because the church of the English rulers, definitely Protestant, not Anglo-Catholic. Just like in England it kept all the medieval cathedrals and parish churches but again the religion was Protestant.
Anglo-Catholicism began in England in the 1800s, ironically as partly a reaction to Britain giving Catholics the vote so the government sensibly decided to shut down four Irish Anglican dioceses since the Irish didn't go to those churches; the Anglican churchmen who started Anglo-Catholicism protested that their church has divine authority so the state can't do that. Their movement never took in Ireland; neither the Anglicans there nor the Irish Catholics wanted it. And anyway, the later Anglo-Catholics, in historical irony, ended up imitating the Catholic Church and weren't interested in trying to convert Irish Catholics to their church. So no, they never built neo-Gothic churches there to try to convert the Irish.
Rite controls what you do in church, for good order. Devotion is freestyle. Latinizations are fine as long as they're old, don't take over from the native rite, and aren't imposed on people when the native rite has perfectly good practices.
