Orientales omnes Ecclesias
Latin for 'All the Eastern Churches'
Encyclical of Pope Pius XII
Signature date23 December 1945

In his encyclical, Pope Pius XII explains that many trials and persecutions took place in the last three hundred and fifty years, but that the Ukrainian Greek Catholic Church always came out strong. He reminds of the many favours and assistances the Church received from Rome and how his papal predecessors always supported the independent culture and rite of the Oriental Church. In the last part of the encyclical, he addresses the grievances facing the Ukrainians in 1945. Aware of the persecution of the faithful and expecting even more, he writes:

  • We know that grievous snares are being set for your faith. We have reason to fear, that in the near future still greater hardships will befall those who refuse to betray their sacred religious allegiance. (Orientales omnes Ecclesias, 62)
