This is what we do, even if it’s for someone who died hundreds of years ago.
Did you note this in the Cardinal’s comment?
“It is a prayer that arises from the very core of creation, the cry of the Word returning to the Father and carrying within it the totality of that creation, marred and broken in its history, yet still longing for the completion for which it has been created.”
When we are worshipping as a community focused on the Eucharist at the Liturgy, we are, fallen as we may be, actually, tangibly approachinmg our created purpose, which, as +Athanasius the Great said, to be become like God. What the Cardinal noted is the very purpose of The Church.
It was not a Catholic Mass though, it was some mix of Catholic and C of E service - England, apparently, refusing to let the last English-Catholic king to die in battle to have a Mass. Oh, well.
