I recently (finally) finished reading the Holy Father's letter on the Rosary, Rosarium Virginis Mariae, which he promulgated last October at the beginning of the 25th year of his pontificate.
I have to say, it is a terrific document... JPII demonstrates the Christocentric nature of the Rosary, showing how the Rosary is a prayer by which we come closer to Jesus.
I have to confess, my use of the Rosary in my prayer life is very, very inconsistent. But this letter made clear to me how the Rosary can help my conform myself to Jesus Christ, and as such, I'm going to make a greater effort to make it a part of my prayer life.
I'd highly recommend reading this document, regardless of what Christian community you belong to.
