"[Pope John Paul II] taught that by understanding God's plan for physical love we could understand "the meaning of the whole of existence, the meaning of life."[62] "The body, and it alone, is capable of making visible what is invisible: the spiritual and divine. It was created to transfer into the visible reality of the world the mystery hidden since time immemorial in God, and thus to be a sign of it."[57]" (http://en.wikipedia.org/wiki/Roman_Catholic_Church#Sexuality)
