Please, what do You think about this idea?
I. Proto-slavic, old slavonic, old church slavonic, old slavonic, neoslavonic
Simply said, this story is very similar to the case with Old Anglo-Saxon and medieval English and modern English, Classical Greek, Byzantium Greek, modern Katharevousa Greek and modern Greek, or with Hebrew languages or Arabic languages etc. It is quite normal, that languages change in centuries.
1) Proto-slavic is a hypothetical common ancestor of all Slavic languages from about 1500 BC to 500. We do not exactly know, if it does really existed, because Slavic language group may be mixture of more ancestors having balanced influences (venetian, thracian, iranian, ...?) and never was with absolutely single language. But majority of linguists work with this hypothesis of the only one proto-slavic language.
2) Old Slavonic is the first known Slavic literacy language from IX century. It has been created by sts Kyrillos and Methodios and their partners for the mission to Moravian Empire. (http://en.wikipedia.org/wiki/Great_Moravia
) This language served about 2-3 centuries not only as liturgical language, but also as the official common written "high language" for general usage not only in Moravia, but also Bulgaria and other slavic countries. Alphabet was Glagolitic. This language influenced national languages (e.g. information flow from OS to national languages).
3) Old Church Slavonic is the medieval and the only liturgical language (from about XIII to XVIII centuries) of the medieval orthodox church. It was direct ancestor of OS and kept almost identical orthography with OS, but was written in Cyrillic, had limited dictionary and reduced grammar. This language lost its universality, because non religious communication has been started in evolving national languages. This language had many dialects (UK, RUS, SRB, BG, ...), because it has been strongly influenced. (e.g. information flow from national languages to OCS)
4) Church Slavonic is the current unified official liturgical language of the orthodox church and greek-catholic church. Of course, it is pronounced with several accents (BG, SRB, RUS, UK, ...) but it has unified cyrillic orthography, grammar and modernized dictionary, which is most influenced by Russian.
5) Neoslavonic is our conlang. It is artificial extrapolation and fixing of the language 2) - OS (not OCS nor CS at all). Neoslavonic conlang project assumes an alternative history where OS language has been evolved parallely with the evolution of national languages and did not stop to play the role of a "high standard understandable language for all Slavic nations".https://sites.google.com/site/novoslovienskij/youtube
II. Does OS belong to the southern branch of languages?
1) There are two myths about OS:
a) OS is old Bulgarian - this is very popular in Bulgaria.
b) OS is old Macedonian - this is very popular in Macedonia (Slavomacedonia).
I do not want to offend anyone at all, but this question is really not simple:
a) The oldest literacy heritage of OS from IXc. proves, that OS is not only very close to the old bulgarian and macedonian, but also has many non "bulgaro-macedonian" elements coming from another archaic slavic populations in Greece, Asia minor, Panonia (this is now Hungary) and Corutania (this is now part of Austria). We exactly know, that there were 7 creators (or first writers) in this language: Kyrillos, his brother Methodios and 5 colleagues (Naum, Kliment, Sava, Angelar and Lazar). They were probably monks together with st. Methodios in the monastery at mount Olympos in Bythinia (Asia minor) and they were from miscellaneous nations - definitely not only pure Bulgarians.
b) Next, OS language coherence (based on the lexicostatistical analysis I described in previous mail) to the modern Bulgarian/Slavomacedonian is less than the coherence between OS and modern Czech, for example. (Czech has very similar noun, pronoun and adjective declention patterns and also has closer vocabulary and closer prepositions. The only feature, where Czech is less coherent with OS than Bulgarian is the verbal system, but early medieval Czech had also the same verbal system, which still exists in Bulgarian.) The same very high level of coherence with CS has also Slovak, Rusyn and Slovenian.
c) More intensive OS language use in southern slavic coutries started later - after the death of st. Methodios when slavic liturgy in Moravia has been disabled and replaced by latin by the Pope and OS awared people (priests, students, ...) were expelled from Moravia away. This started intensive usage of OS in Bulgaria, Macedonia, Serbia and other south slavic states. And yet bit more later also in Russia etc. There this language has been changed through OCS to CS.
d) We know, that glagolitic alphabet has been created artificially by st. Kyrillos. This alphabet is very original, some characters are coming from miscelaneous oriental alphabets and byzantic astrological and philosophical symbols (for example letter S (S means slovo=word=logos) is a vertical combination of a triangle (the God) over a circle (the Earth) and it looks like a fish (another christian symbol). The letter I is vertically reversed S and two letters IS (Jesus) creates nice picture of two fishes = astrological constellation of the Christian age, etc. etc.) This new original alphabet was directly ordered by the moravian ruler Rostislav, who asked to build a strong and independent state and therefore could not directly take either Latin or Greek alphabet. In early medieval it was not like today: Taking alphabet of somebody else significantly weakens the independence on him. It also explains, why Bulgarians (which were dependent on Byzantium) changed the alphabet to Cyrillic (which is in fact the almost unchanged Greek alphabet with some additions). So, if we know, that the OS alphabet has been designed by an extra reason, why would be the language itself the same as the language in Bulgaria - language of the good neighbor, but still competitive state to Moravia!?
All these arguments convinces me that OS was kind of something, which today we call an conlang and initially fulfilled its role very well. Later, unfortunately, this concept has been interrupted and Slavic nations were separated into different cultural areas (e.g. roman catholic - orthodox schism, Islam invasion into the Europe, ...) without the possibility of wider cooperation among them.
These thoughts are not mine. I got them from various readings, and especially from my private discussions with one of the greatest experts on the history and Slavonic Studies - greek professor Antonios-Aimilios Tachiaos. He studied almost all slavic and byzantium sources in original and wrote many books about it: http://www.protoporia.gr/author_info.ph ... _id/908134

Zhuravlev, Anatolij F. 1994. Leksiko-statisticzeskoe modelirovanie systemy slavjanskogo jazykovogo rodstva. Moskva: Indrik. Formula of the lexicostatistical model at page 63.
This is based on the deep lexicostatistical test made from the etymological dictionary of slavic languages in 15 books (ed. O.N. Trubachev, Moscow 1974).
There is a complex formula how to compute statistical distance of languages:
G(A,B) = SUM i is from 2 to n ((n + 2 - i) * V(A,B)i) / H(A) / H(B), where
A,B are tested languages,
n is total number of tested languages
G(A,B) is congruence of these two languages
H(A), H(B) is inherited dictionary from common root of these two languages
V(A,B)i is isoglossa
In the Zhuravlev's formula, the higher value has isoglossa limited to only two languages and the lower number has isoglossa, which is common for more languages from the tested group.
The highest number of proximity is between upper and lower lusatian sorbian: 1.93,
Bulgarian-Slavomacedonian has 1.73,
Czech-Slovak has 1.36,
Bielorusian-Russian has 1.27,
Ukrainian-Russian has 1.20 (but ukrainians learn Russian as well) and
Polish-Bulgarian has only 0.93 etc.
If languages have proximity at least 1.1, they can be assigned into one group, but this approach goes intoa lot of such similar solutions.
For mutual understanding of ordinary people You need to have at least 1.2.
Old Slavonic has value 1.15 (to Polish) or better (1.27 to Czech, for example) to modern slavic languages.
