1 Corinthians 5:7-8: "7 Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. 8 Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth."
Ephesians 5:2: "And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God."
Romans 12:1-2: "1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect."

The text from 1 Corinthians appears in the first verse: "Our Paschal Lamb, that sets us free, / Is sacrificed." I'm not sure if the context matches, but "the festival" might be what the hymn refers to as "the feast" in verses one and two ("O keep / The feast of freedom gallantly" and "Let all our lives now celebrate / The feast").
"Walk[ing] in love" from Ephesians 5:2 is referred to in the second verse: "Let love grow strong anew, and great."
The cited verses from Romans seem to appear in the third verse. "Present[ing] your bodies as a living sacrifice" seems to be expanded into "Let all our deeds, unanimous, / Confess Him as our Lord."
