In the 2nd century C.E., when Christianity emerged as a religion, theologians such as Justin and Chrysostom interpreted Paul’s letters to mean that Christians with faith in Jesus are Abraham’s spiritual descendants through Sarah. Jews, in contrast, are only his flesh descendants, banished like Hagar. Genesis Rabbah responds that after Sarah’s death, Abraham remarried Hagar—now called Keturah, “adorned” (kitra) with commandments and good deeds—and had many more children with her than he did with Sarah.
