Christ is Risen!
This is the same case with Saint Nectarius of Aegina, regarding his glorification. And, yes, the newspapers were very active at Saint Silouan's times. If you read his life, you would find out that many monks came to Elder (Starets) Silouan asking him why isn't he reading the news so he can pray for the world. And, at Mount Athos, the actual renovations that were happening in the Church was being heard by Mount Athos, when the Fathers decided to come together and discuss wether they should do the walling-off of the EP. So technically, even at Saint Silouan's time, Ecumenism was very much known on the Garden of the Theotokos.
