What changes did Ruth make in her life after Mameh died? chapter 21 and 22

Ruth met Dennis and started going to the Metropolitan Church in Harlem, where Reverend Brown was the well-loved minister. Ruth says, "that's when I started to become a Christian and the Jew in me began to die." She then describes an incident when Mameh was waving a live chicken over her head, and told Ruth that death to the chicken would give her life, and that a bird that wasn't able to fly wasn't special anyway.
