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.
