The ancient Romans were very legalistically minded. When they prayed to the Gods, they did their best to ensure that they covered everything; that they addressed the Gods by the right titles (and all of them) so that they could be assured that they were heard; that they asked for everything that they required so that an accidental omission would not frustrate their petitions. Christine Mohrmann showed that there is more than a little of this attitude in the prayers which comprise the Roman Rite of the ancient Latin Church.
In the Canon of the Mass, perhaps this is shown most clearly in the word 'adscriptam'. It means, I suppose, "written on the list". It's lawyer-like. If something's in the Statute, in the inventory, then it's covered. If not, not. We pray that our oblation be "written up". The old ICEL version simply ignored the word; the new ICEL, currently in use, renders it "acknowledged", which is still a trifle coy.
It is not difficult to understand the nervousness of the translators. "Legalism" is not instinctively seen as a virtue in modern culture, still less in modern religious thought. God is not, we feel, a crabbed old backwoods attorney or solicitor just looking all the time for an opportunity or a pedantic excuse to catch us out. He's loving, merciful, generous, understanding. Perhaps, it is suspected, the authors of the Roman Canon were a little bit too Roman and a little bit less Christian than they should have been.
But No. Long before the Roman Canon was written, S Ignatius of Antioch wrote that the Eucharist had to be celebrated by the Bishop, or by one to whom the bishop committed it, for it to be bebaios: a Greek word meaning sure, certain, secure, safe. Conditions have to be fulfilled. To some, this may seem like Legalism. But it is a principle which in turn is based on two root principles of our Faith.
God is true and will do what he has promised. We are called to be faithful and to do what he has commanded in the way that he has commanded. When we are obedient we know that what we have done is official, valid, in the archive, stamped by the clerk.
Praise to him for his faithfulness.
