In biblical context, the term “bastard” (Hebrew: mamzer) refers to a child born outside of a legitimate, God-ordained union—especially through incest, adultery, or unlawful relationships. This was not merely a social label, but had significant spiritual and covenantal implications in ancient Israel.
1. Old Testament Context: The Law and Legitimacy
God gave the Israelites strict commands regarding sexual purity and marriage. They were prohibited from marrying outside of their covenant community (Deuteronomy 7:2–3), engaging in incest (Leviticus 18), or committing adultery (Exodus 20:14, 17).
Deuteronomy 23:2 states:
“A bastard shall not enter into the congregation of the Lord; even to his tenth generation shall he not enter into the congregation of the Lord.”
This meant that anyone born from an unlawful union was barred—along with their descendants—from fully participating in the covenant community (e.g., temple worship or leadership). This law was part of a broader holiness code meant to preserve the sanctity and identity of God’s people (Leviticus 20:26).
Such exclusions extended even to those with physical impairments (Leviticus 21:17–23) or diseases like leprosy (Leviticus 13), showing that ritual purity pointed to a deeper spiritual truth: only those made holy by God could enter His presence.
2. New Testament Fulfillment: Spiritual Illegitimacy and New Birth
Under the New Covenant, the focus shifts from physical lineage to spiritual status. Jesus Christ fulfills the law (Matthew 5:17) and removes the barriers that once kept people from approaching God.
Now, a “bastard” in the spiritual sense is anyone who has not been born again through faith in Christ. Jesus emphasized this when He spoke to Nicodemus:
John 3:3–5
“Very truly I tell you, no one can see the kingdom of God unless they are born again… unless one is born of water and the Spirit, he cannot enter the kingdom of God.”
To be born again means to undergo a radical transformation through repentance, baptism in Jesus’ name, and receiving the Holy Spirit (Acts 2:38). This new birth brings a person into legitimate sonship with God.
3. Illegitimacy and Discipline: A Mark of True Sonship
The epistle to the Hebrews draws a sharp line between true children of God and spiritual bastards:
Hebrews 12:6–8
“For whom the Lord loves He chastens… If you are not disciplined—and everyone undergoes discipline—then you are not legitimate, not true sons and daughters at all.”
In this passage, the word “illegitimate” is used metaphorically to describe those who lack the Father’s discipline—proof they do not truly belong to Him. True children of God not only receive His love and promises but also His correction and sanctifying discipline.
4. Born of Incorruptible Seed
Peter reinforces this truth:
1 Peter 1:23
“For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.”
The “imperishable seed” refers to the new spiritual life planted by the Word of God. Unlike the old, corrupt nature that leads to spiritual death, this seed results in eternal life and legitimate standing in God’s family.
5. From Illegitimate to Inheritor: God’s Redemption in Christ
The grace of God transforms the outsider into a beloved child. Paul teaches that in Christ, former distinctions—ethnic, social, or moral—are erased:
Galatians 3:26–28
“So in Christ Jesus you are all children of God through faith… There is neither Jew nor Gentile… for you are all one in Christ Jesus.”
Even those once rejected, like the Gentiles or illegitimate, are now invited into God’s household through faith.
6. Final Reflection: Have You Been Born Again?
Spiritual legitimacy before God comes only through the new birth. It is not about our natural origin, but our transformed identity in Christ.
Titus 3:5
“He saved us, not because of righteous things we had done, but because of His mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit.”
Conclusion
In the Old Covenant, a bastard was excluded from the assembly of God. In the New Covenant, exclusion is no longer based on physical birth but on spiritual rebirth. If you have not been born again—through repentance, baptism in Jesus’ name, and receiving the Holy Spirit—you remain spiritually illegitimate.
But the good news is that through Jesus, you can become a legitimate child of God today.
Maranatha! (Come, Lord Jesus!)
