Ukrainian Hutsuls are not only Greek-Catholics , there are also many Orthodox Christians.
And the Hutsuls themselves live in several countries in the Carpathian region.

I think that Hutsuls ( the mountains people/the highlanders) also have their own characteristics distinctive from the rest.
The Ukrainian Carpathia gave to Ukraine a lot of talented individuals; priests, state-builders, thinkers-ideologues, poets, writers, artists, and healers.
Ukrainian Byzantine Catholic Church, which the Ukrainian Hutsuls largely confess, historically played important role in the state-creative(state-building) processes.
And if you know from the history about the brave attempts for an independent state in the last century, which eventually bore fruit, after the official proclamation of Ukrainian independence.
The religious scholars in Ukraine give a special attention to the study of Hutsul spirituality, mythology, traditions and rituals of the calendar.
For example , the traditional Christian songs and rituals during Christmas and Easter are slightly different from those of the lower reaches of the Carpathian region.
And of course there are many other interesting features.
When my mother for the first time visited the service at the Greek Catholics, it seemed for her that the coming of the Lord is coming.
