Beauty and Solemnity

I remember little of the words of the Mass, but that isn’t important because the priest celebrating it says the Eucharistic Prayer with such beauty and solemnity that nothing else matters. He says it in Latin not English, but pronounces every syllable carefully without a trace of affectation or pomposity, but with great sincerity and beauty. Who is he? Is he the visiting Abbot of a monastery? He has that sort of natural stature.
