Book Review on Pope's Joy

"Christ Our Joy" by Msgr. Joseph Murphy is the first Catholic book request that I successfully made to our local library! Periodically, I receive suggestions from the email list called "Pope St. Nicholas V" at Yahoo Groups. So I immediately checked this out, but found it more academic than I expected (i.e. it took me longer to read it). It is not written by Pope Benedict XVI, but takes quotations from his many writings all his life. He uses 5-6 chapters to show how true joy is rooted in the Trinity. Here are my two favorite bits:
"It must be clear that pleasure is not everything, that Christianity gives us joy just as love gives us joy. But love is also a renunciation of self."
and
"Joy grows and continues to mature in suffering in communion with the Cross of Christ. It is here alone that the true joy of faith is born."
