Maybe it’s it’s Byzcath.com; not sure. But the Society of St. Josaphat have been using the Liturgy that the Ukrainian Catholic Church has been using for centuries. They call such things as devotion to the Sacred Heart, Stations of the Cross, Holy Rosary, the theology of  Thomism, kneeling, using a dead liturgical language i.e. Church Slavonic,  as Latinisms.

Note that many of these changes (a so-called return to pre-synod of Zamosc) came under the conciliar popes and the same hierarchs they appointed. The Society of St. Josaphat is continuing the pre-VII Tradition which was extended into Ukraine into the 1990s because of the Iron Curtain. If the members of the forum in question  are saying that the Society had changed the Liturgy from what they received then they are simply lying.

Apparently, the Society of St. Josephat is real big into the Divine Mercy devotion and JP2's Faustina and feasts and all that.

From what I've seen (which is very superficial and only scratching the surface), I would pick the UGCC over them. The Liturgy in Old Church Slavonic would be great, unless they had Divine Mercy posters floating around...not knowing what to think.

Hi Centroamerica

I agree, that is certainly a problem. I knew about this and I wondered why they would promote this when their benefactors, the  SSPX, were strongly against this false devotion (I’m not sure now?). It’s unfortunately a “devotion” among most Ukrainian Catholics in western Ukraine (be they Society of St. Josaphat or not). But that still doesn’t take away from the fact that “most” in the Ukrainian hierarchy have embraced the errors of Vatican II. 
I agree it’s a case by case basis for choosing where to attend Holy Mass/Divine Liturgy . But from what I’ve seen in Eastern Europe, they (Society of St. Josaphat) are certainly the safest course. The danger of recognizing such men as JPII or Francis as one’s proximate rule of Faith is wreaking havoc in the Eastern Rites and I think the only reason that they have left the Divine Liturgy relatively unchanged (unlike the Novus Ordo) is an eventual schism to “Orthodoxy”. Many Ukrainian theologians are already discussing a “dual form” of Communion between Rome and Constantinople and Met. Shevchuk has at least hinted that this is the direction that the UGCC is headed. Many others have explicitly endorsed this above model. 

There was an article on Rorate Caeli a few years back (click here) but I can give you more recent references if you like. 

And the SSJ is in favor of that because they don't want to admit it, but the Ukrainian Greek-Catholic Divine Liturgy and the Russian Orthodox Divine Liturgy are the exact same, just added references to the Pope.

I forgot to add to this - it should be the "Ukrainian Greek-Catholic Divine Liturgy as celebrated today"

And the Jєω, Lazar Kaganovich.

Yep.
