Thanks to all who left a comment for Sr Patricia. I'm planning to email her these words of support as soon as she gets more settled and has some email access.
When she left Boston yesterday, the whole community gathered to send her off with a lot of love and prayers. She's wanted to be a missionary to another country for a long time, and last summer she made a special retreat to discern if this was what God was calling her to do.
As we hear news from her I'll post it. There's another American sister there, Sr Leonora, who has been there for several years already. The emails from her are quite exciting. Of course in Moscow most of the people are Orthodox, and right now the relations between the Orthodox and the Catholics are tense. So that presents a difficulty, but the sisters have been working on projects trying to build some bridges.
