I have wondered a lot about “why priests sometimes say things that are not “part of the script.”” I think I got some new insights from reading two articles at
www.artofmanliness.com .
The first is
artofmanliness.com/2015/03/03/macgyver-manhood-and-the-art-of-masculine-improvisation/ . The article highlights how valued and admired the ability to improvise is. It begins with the way MacGyver was able to make something out of nothing to escape from a room in the TV show.
I will quote a section:
“Humans prefer communication that seems spontaneous — that’s tailored to the specific circumstances of the time and the audience. Someone who uses the same speech, pick-up lines, jokes, sales pitch, etc. in every situation, often finds that their banter falls flat because it doesn’t best fit the exigencies of the moment. A man who has the core elements of what he wants to say in mind, but then tailors his message to the changing circumstances, is the far more effective communicator.
Creates a memorable, impressive reputation.
The abilities gained by a man who masters improvisation don’t just pay off in the effective actions he is able to perform, but the reputation those actions create for him.”
So I suspect that the Priest does not believe he is going to receive praise like “Well done, Father. You said the black and did the red.” He believes he will be admired for improvising a better way to say and do things than the book has.
A second article is
artofmanliness.com/2013/12/16/the-rites-of-manhood-mans-need-for-ritual/ . Near the end of the article it has a section under the heading “Wither Ritual?”. It discusses why there is less ritual in modern society than traditional societies. Two main reasons are given: “the Protestant Reformation’s movement against icons and ceremonialism and the Enlightenment’s emphasis on rationalism.” Another is “Suspicion of ritual again grew after World War II, in the wake of the way in which ritual ceremonies had been used to solidify loyalty to the Nazi cause.”
I am not trying to argue it is a good idea for the Priest to not follow the liturgical books. Before ordination he takes an Oath of Fidelity saying “I shall follow and foster the common discipline of the entire Church and I shall maintain the observance of all ecclesiastical laws, especially those contained in the Code of Canon Law.” Part of the Code of Canon Law is canon 846 “The liturgical books, approved by the competent authority, are to be faithfully followed in the celebration of the sacraments.” (New Revised English translation, 1997).
But I think that society’s admiration of innovation and suspicion of ritual are factors in problems like those discussed in the 2004 Instruction Redemptionis Sacramentum.
