Link Deut 16:4 & 1 Cor 5:7 on purity?
What connections exist between Deuteronomy 16:4 and 1 Corinthians 5:7 about purity?

The Call to Remove Leaven: Deuteronomy 16:4

“No leaven is to be found in all your land for seven days. And none of the meat you sacrifice on the evening of the first day shall remain until morning.”

• During Passover and the Feast of Unleavened Bread, Israel cleansed every bit of yeast from home and heart.

• Leaven symbolized anything that spreads and corrupts—sin, compromise, idolatry.

• Physical removal illustrated an inner call to holiness: a people set apart for the LORD alone (Exodus 12:15-20; Leviticus 11:44).


Christ, Our Passover: 1 Corinthians 5:7

“Get rid of the old leaven, so that you may be a new unleavened batch, as you truly are. For Christ, our Passover lamb, has been sacrificed.”

• Paul addresses open sin in the Corinthian church (5:1-2).

• He lifts the ancient picture into present reality: Christ’s once-for-all sacrifice fulfills the Passover lamb (John 1:29).

• Because the Lamb has died, believers already are “unleavened” in position; now they must live that purity out in practice.


Shared Symbol: Purity Through Removal

• Leaven in both passages = what defiles and multiplies if tolerated (Matthew 16:6; Galatians 5:9).

• Removal precedes worship: Israel could not eat the Passover until the leaven was gone; the church cannot enjoy fellowship while sin festers.

• Both texts tie purity to sacrifice: Old Covenant lambs point forward; the New Covenant Lamb has come, making purity attainable.

• Seven-day sweep (Deuteronomy 16) foreshadows a continual lifestyle: “Let us cleanse ourselves from every defilement of body and spirit” (2 Corinthians 7:1).


Practical Implications for Believers Today

– Personal Inventory: regularly search for “old leaven” — attitudes, habits, doctrines that contradict Scripture.

– Immediate Disposal: don’t store leftovers of sin “until morning.” Confess and forsake quickly (Proverbs 28:13; 1 John 1:9).

– Corporate Responsibility: local churches guard purity by loving, restorative discipline (1 Corinthians 5:11-13).

– Celebrate, Don’t Mope: removal of leaven isn’t grim—Passover was a feast! Purity clears the way for joyful communion (John 15:11).

– Depend on the Lamb: holiness flows from Christ’s finished work, not self-effort (Hebrews 9:14; Titus 2:14).


Summary of the Connection

Removing leaven in Deuteronomy 16:4 prepares Israel to meet God; removing leaven in 1 Corinthians 5:7 allows the church to live out what Christ has already made her—pure, set apart, ready for continual celebration in His presence.
