Crusoe's Catholocism?

"...whose sprinkling alters us / into good Fridays who recite His praise,/ parroting our master's / style and voice, we make his language ours, / converted cannibals, / we learn with him to eat the flesh of Christ."

I find this section of the first stanza to be interesting because it appears the author is drawing a connection between Crusoe's colonizing influences and the colonial nature of Catholicism. Deserted on an Island, Crusoe firmly believes it is his responsibility to impose his beliefs and his order onto an otherwise lawless and savage world. In pursuit of this goal, Crusoe encounters a native, whom he calls Friday, and appoints him as his manservant with the intent of providing a positive moral influence on Friday's savage nature. Yet here I believe the author engages in a little bit of wordplay concerning the "good Friday"as Good Friday is the day Catholics and many other Christians believe that Christ died on the Cross for our saves, saving us from our otherwise sinful and barbaric nature. The author carries this theme forward, linking the mimicking abilities of a parrot with the Catholic desire to emulate Christ in all his words and actions. Furthermore the author draws an interesting comparison between the redeeming grace of Christ and the Catholic church with the seemingly barbaric practice of the Eucharist which is central to the Catholic faith. Through the practice of the Eucharist Catholics claim to consume the actual corporeal body and blood of Jesus Christ presented under the appearance of bread and wine, a practice instituted by Christ himself at the last supper on Holy Thursday (Christ's last meal before Good Friday). Through his use of alliteration the author provides an interesting insight into the nature of "converted cannibals"; while Crusoe and Catholicism both perceive their efforts as redeeming and refining, to what extent can this binary be turned in on itself? The author's use of jungle metaphors (parrot, cannibals, cannibalism) causes the reader to not only reflect on the nature of Crusoe's "civilizing" efforts but also to re-examine our definitions of the savage and the refined.
