Nie ma za co, Nektariusz!
I would be remiss if I did not mention the devotion of not only the Polish Orthodox AND the Polish Roman Catholics, but of *ALL* Christian Slavs, to two Greek missionary brothers from Thessalonika, Saints Cyril and Methodius, called "Teachers of the Slavs" in Orthodoxy, and their disciples. Under the influence of one of the disciples of the "Teachers of the Slavs," a "Roman Slavonic Rite" was established in parts of what is now Poland (including Krakow)--this according to the RC scholar, Fr. Francis Dvornik, in his great work, "Byzantine Missions among the Slavs." It didn't take Rome too long to suppress the "Roman Slavonic Rite" however---how dare the Polish Slavs of the time have liturgy in a language they could understand!
Finally, one should read the life of St. Maxim Sandowicz, a Lemko-Rusyn Pole and a priest-martyr for Orthodoxy within the lifetime of some of us "older ones." St. Maxim was canonized by the autocephalous Polish Orthodox Church. I have an icon of St. Maxim Sandowicz in my "Thumbs-plus," but I can't remember where I got it.
