This stage, they said, is thanks not only to Pope Francis' meeting with Patriarch Kirill in Havana in February 2016, but is also due to the loaning of the relics of St. Nicholas to Russia over the summer, drawing millions of Orthodox faithful for veneration.

According to an Aug. 23 statement from the Russian Orthodox Patriarchate of Moscow, at the beginning of the meeting Patriarch Kirill said the meeting between he and Cardinal Parolin was possible due to “the development of relations between the Russian Federation and the Holy See.”

“But it is with still greater satisfaction that I see the development of relations between our Churches,” he said, noting that his meeting with Pope Francis provided new impetus for cooperation between the Russian Orthodox Church and the Catholic Church.

“This fact testifies that a new stage has indeed begun in our relations with events of great importance, which have been possible because in Havana we agreed our positions on many current issues,” he said, adding that “this communion of positions allows us to build plans and give them real content.”

Cardinal Parolin echoed the sentiment, offering Pope Francis' greeting to “my brother Kirill,” and affirming the patriarch's observation that the Havana encounter “has laid the foundation for a new stage in the relationship between our Churches, giving new impetus to these relations,” according to Vatican Radio.
