>so where are russian words?

Like, all of them? At least, "words comprehensible to a Russian-speaker".

>Does Russian alphabet have Є letter?

Ukrainian still does. It's closer to the Old Church Slavonic. And the Ѣ was only dropped 100 years ago by the commies.

Regardless, nobody is saying that the beresty are modern Russian, just that it's in a Slavic language (and one comprehensible to modern-day Russian speakers). What's your point, exactly?
