1 Corinthians 5:7-8 reads:
"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."
We know that the early Christians observed the Passover, as well as all of the other feasts and holy days that God had previously ordained. But here is Paul instructing the Christians of Corinth to actually celebrate with new dough, making sure that the old dough has been cleaned out. Meaning that we need to act as if we are new people, but still to celebrate Jesus as our Passover Lamb.
