Song of text

"I am the living bread at comes from heaven."
Our Savior has revealed to His disciples:
"I am the bread that came down from on high.
He who comes to me and receives with love
Will surely live in me for ever,
And will inherit the kingdom of heaven."
"Open, O Lord, the gates of justice for us."
Compassionate Lord, who calls
Sinners to your presence
And opens the doors for repentance
May we enter into your presence
And sing your praises day and night.
