Dogmatically no, there is no holy language in [tag:global-christianity] to do services or to speak in. 

There was a [tag:heresy] called *Three-Language heresy*, according to which it was said that the Christian [tag:church] has only three languages to use in church: Hebrew (not Aramaic), Greek, and Latin. This "[tag:dogma]" was based on the [tag:Bible] words *[Luke 23:38 [tag:KJV]]*:

> 38 And a superscription also was written over him in letters of Greek, and Latin, and Hebrew, THIS IS THE KING OF THE JEWS. 

and *[John 19:20 [tag:KJV]]*:

> 20 This title then read many of the Jews: for the place where Jesus was crucified was nigh to the city: and it was written in Hebrew, and Greek, and Latin. 

So some people have said that since the [tag:Bible] referred to only three languages, so the [tag:church] can use the only those; even when it sends a mission to other non-Christian people, the first task is to teach the people one of the languages, and then preach the [tag:Gospel].

During the times of enlightment of Slavs the [tag:pope] condemned the [tag:doctrine] as a heresy, and recognized the Slavic alphabet as a holy language, however exactly this heresy has been persistently preached by German missionaries, and after a series of discussions sparked condemnation by the Slavic teachers.

However, we need to say that in arguments of the heresy advocates were non-empty. The point is that a human is a complex being, and he understands the meanings of words, of speech, of which he uses not only one level to communicate. So there is a high style, a low or "trade" style of speech, and of course a holy level. And this level of course may be used by a human for prayer, and if human don't use the style, all his life is subject to desacralizations. It is just one the rules for [tag:ascetics]. For example, the Solun brother had known this rule, and created the church-Slavonic language as an *artificial* one based on the Macedonian dialect of old-Slavic language of that time.

In the present time we see the various languages which are used as a sacral languages of a various churches even non-Orthodox, or Catholic.
