Latin might be used if Prince Philip was Catholic (God understands Latin and the prayers are addressed to Him) but he was Anglican and very little Latin has been used for, lo, some 500 years.
Perhaps you don't get out much, a translation from the Latin is always available for those who require it in Church.
I don’t know - the Anglican Church is so much like the Catholic Church these days, hard to tell them apart.
And OBTW, not going to Catholic Church is certainly not “not getting out much”. Hardly. Being free of the Catholic Church is like a breath of fresh air.
