This excellent little book comes in at around 130 pages. It is a little uneven at times, and that might be due to having two authors. In spots, it is sublime.
The premise is that there seems to be a tension between spirituality and formal worship that ideally ought not to be there. The authors attempt to make the case that Christ sought to overcome this split in leaving us the Eucharist. They point out how odd it is that Christ seemed to be against formal ritualism, yet chose to leave us with a rite–just as he was headed for the climax of his earthly mission, the Cross.
They do an inspired job of attempting to get into the mind of Jesus and uncovering his possible thought process. It is the chief surprise of this book and worth reading for that payoff alone.
UPDATE: You will likely notice that the references to the texts of the Mass do not reflect the revision to the English version of the Roman Missal which came out at Advent in 2011.
