The program for Sunday’s papal inauguration liturgy mentions one deacon prominently:

Deacon Teodoro Mandato will take part in the section of the liturgy in which various members of the Church — including, of course, deacons — profess obedience to the new pontiff.

A quick Google search reveals that he was ordained for the Diocese of Rome in 2024. 

And he was featured on Italian television a few months back talking about his vocation. I haven’t been able to find more about him. And my fluency in Italian is, sadly, non-existent. But keep your eyes peeled for him Sunday!
