This past week, April 11-19, members of the Church of God around the world observed the festivals of the Passover and the Feast of Unleavened Bread.
The celebration is a carry-over from the ancient festivals which the Jews and other children of Israel kept, as commanded by the LORD God through His servant Moses (Leviticus 23:4-8). This was to commemorate an important part in the history of the Israelite nation – their deliverance and salvation from their heavy bondage as strangers and slaves in Egypt, ruled by its cruel king Pharaoh.
Exodus 12 details the preparation, sacrifice, and the eating of the Passover lamb. God commanded that some of the blood of that lamb was to be daubed on the lintel and doorposts of the Israelites’ homes. That same night the Israelites were to remain in their homes as God’s death angel went through all the land of Egypt to slay the firstborn of man and beast of the Egyptians. The angel was to spare (or “pass over,” thus the name of the festival) the homes of the Israelites on whose doors was the blood of the lamb.
Because of the slaughter of all of Egypt’s firstborn, the Pharaoh finally agreed to let the people of Israel go out to where God commanded them to go. The next evening the Israelites moved out with their family and possessions out of Egypt, with the LORD God leading and accompanying them with His almighty power.
Exodus 123-14 details God’s awesome, miraculous salvation of the families of Israel through the famous “Exodus” through the Red Sea.
The apostle Paul, having been thoroughly instructed in this Jewish celebration, and understanding that the lamb slaughtered on the Passover pictured the eventual sacrifice of Jesus Christ on the cross at Calvary as the “lamb of God who takes away the sin of the world” (John 1:29, 35), wrote to the members of the Church of God at Corinth:
For indeed Christ, our Passover, is sacrificed for us. Therefore, let us keep the feast [of Unleavened Bread], not with the old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth (1 Corinthians 5: 6).
Paul understood that sin [malice and wickedness] is symbolically like Egypt which enslaves us (Romans 6:20 – “servants of sin” here being translated from the Greek doulos, meaning “slave”).
Leaven of malice and wickedness
Paul had just addressed a serious problem among the Corinthian brethren. A member had been committing sexual immorality with his “father’s wife” (Verse 1) – actually the man’s mother-in-law! Paul censured the brethren for their failure to reprimand or discipline the erring member, and their being “puffed up” about it (Verse 2) – they tolerated and even boasted about the happening.
Paul strongly urged them to put away their erring brother from their fellowship, so that he might realize the weight of his sin and repent (Verses 4-5).
Paul then explained why it was necessary to put away [in church language, “disfellowship” or “excommunicate”] the sinning brother. “Do you not know that a little leaven leavens up the whole lump” (Verse 6)? If they did not take steps to disfellowship the erring brother, his sin would be taken lightly by the other brethren, and this could cause them to be careless about sinning in their own lives. Just like the effect of leaven on a lump of dough!
Paul and Jude describe the way sin creeps into men, and even into the Church of God — like leaven! “And this occurred because of false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage) to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you” (Galatians 2:4-5). “For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of God into lewdness [a form of lawlessness] and deny the only Lord God and our Lord Jesus Christ” (Jude 4).
It was with the same subtlety [or stealth] that Satan, masquerading as a serpent, got Adam and Eve to commit the first human sin at the Garden of Eden (Genesis 2-3). [See: “Your Eyes Will Be Opened!”]. Eve was caught unaware that she was being tricked by the devil with his doubting question: “Has God indeed said ‘You shall not eat of every tree of the garden’” (Genesis 3:1)? This was contrary to what God had told Adam [and what Adam, told Eve, too], “Of every tree of the garden you may freely eat, BUT of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die” (Genesis 2:16-17; compare with Genesis 3:2). [See: The Deceitfulness of Sin.]
The apostle Peter admonishes us: “Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour” (1 Peter 5:8). He counsels us: “Resist him, steadfast in the faith. Knowing that the same sufferings are experienced by your brotherhood in the world” (Verse 9).
Therefore, we should pray for ourselves with Peter: “But may the God of grace, who called us to His eternal glory by Christ Jesus, after you have suffered a while, perfect, establish, strengthen and settle you” (Verse 10).
The apostle James also admonishes us: “Therefore submit to God. Resist the devil and he will flee from you. Draw near to God [in prayer] and He will draw near to you” (James 4:7).
For many years, it was my practice [as it was with other Worldwide Church of God members] during the seven-day Feast of Unleavened Bread, to check the ingredients of food (like biscuits or crackers) to see if there was any leavening in them before I bought and ate then during that period. As God commanded, we were careful to remove all leavening and leavened roducts from our homes, as leaven symbolized sin during this festival.
Paul charges us: “Test [KJV, “Prove”] all things, hold fast what is good. Abstain from any form of evil” (1 Thessalonians 5:21-22). Likewise, the apostle John: “Beloved, do no t believe every spirit, but test the spirits [thoughts, ideas put forth to us], whether they are of God; because many false prophets have gone out into the world” (1 John 4:1).
We cannot properly test the spirits unless we are guided by God’s Holy Spirit in understanding God’s word (1 Corinthians 2:11-12). [See: God’s Spirit and Obedience.] Isaiah 8:20 should guide our testing: “To the law and to the testimony [prophecy, Revelation 19:10]. If they speak not according to this word, it is because there is no light [truth] in them.”
Paul rightly charges: “Therefore let us keep the feast [of Unleavened Bread, showing that it is for Christians, not just Jews, to keep!] … with the unleavened bread of sincerity and truth” (1 Corinthians 5:8).
We are to be sincere – whole-hearted – in seeking and obeying and living by [as bread or food, Matthew 4:4] every word of God – His truth (John 17:17), and His law (Psalm 119:142).
But why is the kingdom of God likened to leaven?
It might confuse some to think that, if the Bible looks at leaven as a type or sin, why did Jesus, in a parable, compare the kingdom of God to a woman taking three measures of meal or flour and working each one with leavening (Matthew 13:33)? He even warned His disciples about “the leaven of the Pharisees and Sadducees” (Matthew 16:11), and meant it to be their false doctrine (Matthew 16:11-2), their hypocrisy (Luke 12:1)?
To understand this seeming contradiction, we have to look at another of Christ’s parables comparing the kingdom to: the parable of the “mustard seed” (Matthew 13:31-32). Here Jesus explains that, like the littlest of seeds, the kingdom of God starts small and gradually grows until it covers the whole world – just like a little leaven leavens a whole lump of dough.
This website has been set up to help visitors and readers to have their eyes and hearts opened to understanding and living by God’s word and truth [see: About Pool of Siloam]. We hope and pray that through the articles here (now more than 150) you will grow in grace and knowledge of our Lord and Savior Jesus Christ (2 Peter 3:18)!
God bless you all!
