Adam’s setting below is far preferable if you can manage. Every single word of this antiphon is important. It comes straight from the Gospel and is a perennially vital expression of the Petrine ministry.
For those parishes that are not able to sing plainsong yet, please feel free to use this Long Meter version of the Entrance Antiphon.
And you are Peter, Jesus said.
My Church is built upon this rock.
The gates of hell shall not prevail.
The gates of heav’n you shall unlock.
