Their salvation is very much on the line. It is difficult enough for a Catholic. It is likely, too, that many of them are not invincibly ignorant just as many are. No doubt an excessive love of family and national pride keep many ensnared and closed to the truth.
Hi Recent. (Welcome back!)
I see your POV. There is always a possible risk in any talks with non Catholics, of enabling Indifferentism. I know many people, Catholics and others, who believe the sole purpose of religion is to give you peace, and encourage friendliness. They reject all dogmas and religious authority, including Scripture and Tradition. Yes, indifferentism is a problem.
Yes, I share your concerns about, specifically,
Russian Orthodoxy. Unlike Orthodox Christianity in many countries, it went through generations of a brutal national ideology which even now still has lingering tentacles everywhere. Looking for perfect people? Not there. Yes, I have read about the KGB infiltrating the church, for decades.
I also do not think any other faith is equal to the fullness of faith in the RCC, with the Magisterium. Having said that, other Christians do share much of the truth of our faith, none more so than Eastern Orthodox. In many places in Europe and other continents, it is the Eastern Orthodox, sometimes in combination with RCC, who uphold some remnant of Judeo-Christian civilization against a tidal wave of secularism. Millions of people have lived and died, who never heard the faith directly from the RCC, but did receive the gospel - mostly what you and I believe - from the EO. I praise God for that.
I do not know if the Catholic parishes in my comfortable suburb would have survived a century of Communism. The pope would be a fool if he was not curious enough to ask someone who might tell him something Pope Francis would like to know. Given that the Church in the West may soon be in a situation of persecution by the government, that information, that testimony of their Russian experience, is crucial. New relationships, friendships and cooperation, are needed, in Russia, and here.
Prayer for the Pope is needed, along with prayer for all church leaders.
