Jesus, save my sis

Does anyone know the patron saint of sisters?

My sister Carrie dissagrees with the Church on multiple things, like praying to saints, and she thinks that the concept of the Eucherist being the body of Christ is creepy. My other sister Nora and I tried to explain about the saint thing, but she doesn't seem open to it. I didn't even defend the Eucherist because I didn't know what to say to that. I love her to death and it really hurts to see her not believe in the Church. I think she believes and loves Jesus, but other than that I don't know. Please pray that she comes back.
