But this isn't ancient Greek.

Yes I know about the Erasmus pronunciation and that it does not conform to how we talk nowadays. And I know most Greeks haven't ever heard about his theory. And I say theory because not everyone agrees with his proposed pronunciation.

But this here is another matter. Biblical texts are not in ancient Greek.

Edit: I actually said that the biblical texts are not in ancient Greek (in that the language had evolved from the time of Plato and other such texts) but to be honest I wasn't really sure about my statement. I tried to do a quick research and I might have been mistaken.

However about this particular prayer, although it is of course not in modern Greek, I do not think there are particular hard passages that are not understood without knowing any ancient Greek.

To build a bit further on this. The new testament is written in Koine Greek (Common Greek) https://en.wikipedia.org/wiki/Koine_Greek . A lot of the phonological changes from attic to modern have already happened by the time these text were written.

For most Greek speakers texts from this time are mostly legible, words like epiousios not withstanding.

Additionally I would like to point out that pronunciation has little to do with comprehension of written texts.

Is this true? As someone who studied classical Greek, I can mostly understand NT Koine OK, but most of modern Greek goes right over my head. Conversely (anecdote alert) I watched a YouTube video where a Greek guy took ancient texts out onto the streets of Athens and asked people to make sense of them; most people giggled self-consciously and admitted that while they had studied them in school they were able to make very little headway in actual translations.

Edit: so my point is that, to my naïve eye, Koine seems much closer to Attic than to Modern, and hence I'd expect modern Greeks to struggle with it - but would be very interested in being proved wrong :)

In my own limited experience in school, I found texts from the first century AD much easier to comprehend than say the odyssey, or even classical texts.

But still it was an academic exercise, it required attention and some time, it was far easier than classical texts yet not something you can do in the street on the fly.

I may have to pull back from mostly legible to mostly decode-able. ;)

I only really know some classical texts and, for Koine, just the NT, but the structure of the NT is so much more straightforward to understand - it's basically this happened, then that happened, etc etc and there is none of the "decoding" that you often have to do with the classical stuff. But I am fascinated by how much of this is intrinsic to the language and how much is down to artifice on the part of the classical writers. In other words, the audience for the NT is ordinary folks whose first language in many (most?) cases is not even Greek, so the message has to be written as plainly as possible (and actually the prose is kind of pedestrian as a result IMO). But what's the situation with classical authors? Are they really reflecting the speech of the time or are they using a more complex and artificial form of language divorced from daily speech? I don't know - I think there must be an element of it, but otoh someone like Aristophanes is trying to make audiences laugh so the language has to be relatable and idiomatic you would think.

This, exactly. The Greek alphabet is much older than Koine Greek, of almost 500 years. While spoken language tends to change fast, written language tends to stick and doesn't easily change, for obvious reasons (just look at English or Tibetan). People won't change how they write some word just because they pronounce it differently from the past, because that would make the text much harder to read.

Also, /b/, /β/ and /v/ have the tendency to get swap with each other in lots of languages, and most people fail to distinguish them apart unless their language imposes a clear distinction among them. See for instance how Italian or English distinguish /b/ from /v/, while /b/, /β/ and /v/ are all basically the same thing for a Spanish speaker.

Indeed Koine Greek is not ancient Greek, and while also being different from modern Greek, it's also different. The main difference being that Koine stems from the attic dialect and modern Greek from the dimotic dialect. To make matters even more complicated, the transition to make dimotic official happened in 1979 and thus there is still a living generation accustomed to read and write Koinè/kathareuousa Greek.

This familiarity didn't end overnight and as these things often do they live on in a long tail, see for example Russian influence in many ex-soviet republics which is only waning with the youngest generations, or for example German influence that lasted in northern Croatia way longer than the austro-hungarian domination.

That said, linguistics is full of traps. The common person on the street makes all sorts of assumption based on modern facets, often inverting the relationship between Prestige/low-education/provinciality with historical language change, i.e. often assuming that the poor illiterate provincial people are those who talk badly and distort the language, while in reality they often preserve archaic forms in some cases (while innovating in others).

An example from contemporary coastal Tuscany in Italy: in the local dialect the word for rabbit is "cunigliolo" while the offician Italian is "coniglio". If you ask a random person from the street they would tell you that "cunigliolo" is not only an uneducated form but actually a silly deformation of the right word and that it's obviously so, because the suffix "-olo" sounds funny (probably because of the influence of the names of the seven dwarves in Italian, brontolo, cucciolo, mammolo, pisolo, ... all designed to sound cute to the ear of a modern italiano speaker).

Turns out that the latin word for rabbit is "cuniculus".

Now, did I say that linguistics is tricky? Turns out that the "-olo" suffix has been added to other words as well, like "ragnolo" which has no etymological explaination. They could be an innovation to regularize the perceived "funny local way of saying rabbit", perhaps modeled on the 7 dwarves, or not. Perhaps cunigliolo etymology is also wrong and I'm grasping at straws, but I think my main point still holds: don't trust the gut reaction of native speakers for anything other than their living language.
