Why does Joseph’s lineage in Matthew 1 matter if Joseph wasn’t Jesus’ biological father?
Professor Diane Jacobson reveals how this apparent contradiction actually unlocks the key message of Matthew’s Gospel. Through adoption, Jesus becomes the son of David, demonstrating that God’s family extends far beyond bloodlines to include all who are claimed and named as God’s own.
The Joseph lineage Bible passage also features five remarkable women – Tamar, Rahab, Ruth, Bathsheba, and Mary – whose stories of survival, courage, and faith show how God works through unexpected people. From foreign women to those with questionable reputations, these ancestors reveal that Jesus came for everyone, including those society might reject. This conversation transforms a seemingly boring genealogy into a profound theological statement about divine inclusion.

- Luke 3:23-38
- Five women mentioned in Matthew’s genealogy:
- Tamar: (Genesis 38) becomes pregnant by her father-in-law, Judah, who admits: “She is more in the right than I, since I did not give her to my son Shelah.”
- Rahab (Joshua 2)
- Ruth: Moabite woman, which was a neighbor that the Israelites hated
- Wife of Uzziah (Bathsheba): Not mentioned by name
- Mary
- Matthew 1:19-25: Joseph is commanded by angel to stay with Mary, and when Jesus is born, he takes the child and names him — similar to Pharaoh’s daughter adopting Moses.
HERE ARE 3 KEY TAKEAWAYS FROM THIS EPISODE:
1. Adoption is as Real as Biology in God’s Family
The most profound insight is that Jesus becomes the “son of David” through Joseph’s adoption, not bloodline. When Joseph names Jesus, it’s an act of adoption – just like how Gentiles become God’s people “by adoption.” This challenges our assumptions about what makes family legitimate and shows that God values chosen relationships as much as biological ones.
2. God’s Family Includes the Unexpected and Marginalized
The five women in Jesus’ genealogy (Tamar, Rahab, Ruth, Bathsheba, and Mary) were all foreigners, outsiders, or had “questionable” circumstances. Yet they’re specifically highlighted in the family tree of the Messiah. This isn’t accidental – it’s Matthew’s way of showing that Jesus came for everyone, especially those society overlooks or rejects.
3. What Looks “Wrong” Often Reveals God’s Truth
Each woman’s story appears scandalous on the surface – prostitution, deception, foreign origins, adultery, mysterious pregnancy. But when you dig deeper, these women were actually acting righteously, protecting their families, and demonstrating faith. The genealogy teaches us to look beyond appearances because God often works through what the world considers illegitimate or improper.
