Does the Catholic church believe they need to sacrifice Christ again?

[Jayne_Maser]

Why in communion does the Catholic church believe that they need to sacrifice Christ again? I am a life long Lutheran who is considering converting, but I have many questions.
Thank you for you time and consideration.
