You have to be more specific as to what you mean by the "Byzantine Empire". If you are asking about the eastern part of the Roman empire, which historians have dubbed "Byzantine" (after the city of Byzantium), be aware that there was no such thing. It was the Roman empire-- period. Historians used the term Byzantine when they were referring to the eastern parts of the Roman empire in order to differentiate between the two areas of the empire.

1) Byzantine missionaries spread Orthodox Christianity to Serbia, Bulgaria, Romania, Moldova, Ukraine and Russia. 2) Byzantine church architecture influenced church architecture in the mentioned areas. 3) After the fall of the Byzantine Empire, the Tsar Ivan III, who had married the niece of the last Byzantine emperor, saw himself as the successor of this empire. Some Orthodox Christians then nominated Moscow as the third Rome. Russia was called for a period of time "The Third Rome."
The Byzantine Empire in its heyday covered parts of Italy, the whole of Greece and the Balkan countries, Turkey, parts of what now is Syria and the Lebanon, and large coastal areas of northern Africa. The result was of course a mix of the many peoples that lived there and their cultures. The court culture also was a mix, in this case of Latin an Greek.
Slavs definitely. Silly answer The highest Church official was the Patriarch, who was considered superior to all the Archbishops and bishops. When the Byzantine empire still controlled all the areas of the Levant and North Africa there were other Patriarchs at Antioch, Jerusalem and Alexandria. As he was in the imperial capital at Constantipole he was considered the most important when they met in Council. After the Muslim invasions the other patriarchs have dwindled to unimportance. The current Patriarch has a very small congregation in Istanbul, after the Greeks were expelled at the end if the first world war. He is still considered the head of the Orthodox Church, though the patriarch in Moskva controls far more adherents.
The western part of the Roman Empire disintegrated under the wight of the Germanic invasion. The eastern part of the empire was distant from these areas of invasions and was not affected by it. Byzantine Empire is a term which has been coined by historians. The Romans called it Roman Empire. The term refers to the eastern part of the empire after the fall of the western part. It is used to indicate the fact that after it lost most of its non Greek territories (because of invasions by Arabs and Slavs) it became centred on Greece and Greek in character. Greek replaced Latin as the official language of the empire in 620. The term Byzantine is derived from Byzantium, the name of the Greek city which was redeveloped and turned into the capital of the eastern part of the empire and renamed Constantinople.
