Justin takes an interesting twist in sections 131-140. I also think I'm nearing the end of this dialogue and about to enter into his next work on CCEL.
He starts with Jacob's marriages to Rachel and Leah and how they also point to Christ. I know a lot of Old Testament things point to Christ. There may be reference to Christ in this, too. However, I cannot see it pointing to Jesus the way Justin describes. He claims that Leah symbolizes Israel and Rachel symbolizes the complete church. There is so much wrong with that. Judah, the tribe that Jesus is from, came from Leah. The beginning of the Christian church came through Leah's line. Rachel was the one who loved Jacob but kept stealing fertility idols in order to get pregnant, not trusting in Jacob's providence. This action eventually got her cursed unwittingly by Jacob when Laban was looking for the idols, and she died the next time she bore a son.
Laban tricked Jacob into marrying Leah first when he wanted Rachel. God was never tricked. He created Israel, according to Justin, named the nation for Jesus himself, the overcomer of power. Then Jesus was physically born on earth as a man, lived all of God's laws, suffered the punishment for his fallen people, and then rose from the dead. The Church is now the completion of Israel. I just don't see how Leah and Rachel's marriages to Jacob could be a typology of the church the way Justin would envision.
He then wanders into talking about Noah. He and Jesus were both saved through water, faith, and wood. God saved Noah from his destruction from water, Noah obeyed him in faith, and the ark was made of wood to typify the cross. Baptism, faith, and the cross are all drawn from this. Jesus came, was circumcised, let John baptize him, then he began his mission to tell all Israel about faith in God and now to be saved, and he died on a cross of wood.
After the flood, Noah proclaims blessings on his sons Shem and Japhath, but he curses Ham. Justin ties this to Rachel and Leah's servants that they gave Jacob as concubines. Rachel and Leah symbolize Shem's blessings to the people officially living in the promised land. Bilhah and Zilpah symbolize Japhath's blessings. He doesn't officially live in Israel but he is still blessed as part of God's family. This shows that Jesus married Israel, and because of Israel, the gentiles are included in the blessing. I feel this is a more accurate analogy thought it is also very twisted. Marriage to Jesus is so much more than marriage to a man such as Jacob. The latter is riddled with sin and perversion. The former is pure, and all people have equal standing with the Lord.
