There are traditionally two Ukrainian churches: The Ukrainian ORTHODOX Church (which this article is about) and the Ukrainian Catholic Church.

The Ukrainian Catholic Church split from the Roman Catholic Church in the 9th Century but then rejoined the Roman Catholic Church about a century later and is part of the Roman Catholic Church today.

Just in case someone get confused with the terms...

Soloviev made a pretty good case that the Russian/Ukrainian Church never formally split from the Catholic Church.

[Verginius Rufus]

The 9th century was before that part of Europe was Christianized.

The major split between the Catholic Church and the Orthodox Church dates to 1054. I believe the Ukrainian Catholic Church dates back to when parts of Ukraine were part of the kingdom of Poland.

They are part of the Catholic Church, but would not appreciate being called “Roman Catholic”.
