Old Church Slavonic also known as Old Bulgarian or Old Macedonian in some contexts, was the first literary Slavic language, developed from the Slavic dialect of the Thessalonica region by the 9th century Byzantine Greek[8] missionaries, Saints Cyril and Methodius, who used it for translation of the Bible and other texts from Greek and for some of their own writings. It played a great role in the history of Slavic languages and evolved into Church Slavonic, which is still used as a liturgical language by some Orthodox and Greek-Catholic Churches of the Slavic peoples.

All the others call it Old Church Slavonic, only the Bulgarians call it Old Bulgarian.

"Thereupon the language, in its Bulgarian recensions, spread to other South-Eastern and Eastern European Slavic territories, most notably to Croatia, Serbia, Bohemia, Lesser Poland, and the Russian principalities."

HAHA, I posted a link, was not my point to copy everything, my point is that Macedonian could be referred to something Slavic and not Greek.
