My Brother's Priestly ordination.

Good Day Fathers of r/AskAPriest!

I had the opportunity to witness yesterday the ordination of my brother to the sacred orders of Presbyters. After 10 long years, it is done. It was truly a great occasion and I gotta admit I got teary eyed.

I could probably get some answers on the internet but I would love to hear directly from you Fathers.

What's the story behind kissing the hands of the newly ordained priests? And what prayers or what were you reciting when you put your hands above his head?

I feel a bit ashamed because I feel like I should know this, being a brother of a priest but many things were so novel to me. Thank you in advance and God bless you all!
