This understanding is lacking in both world-orthodox and in the zealots. They are outside the Church, so they are outside the experience of the Church, and they only have a vague idea of the Church.
To understand Fr. Seraphim to any significant degree, we must see the Church as he saw it and particularly the Russian Church. Fr. Seraphim's idea of the Church was clear, it was imparted to him by St. John Maximovitch. Here are 3 essays that can help us see the ROCOR as Fr. Seraphim saw it, as St. John taught it:
I maintain and assert that without a deep understanding of the Russian Church, it is possible to understand Fr. Seraphim. (Same with understanding St. John S&SF.) Therefore, world-orthodox (apostates) and zealots (schismatics) are unqualified to tell us about Fr. Seraphim, to speculate where he would be today if he were alive.
Platina's idea that the Orthodox experience goes beyond Fr. Seraphim is pure folly. Fr. Seraphim made it to heaven. What greater experience of our faith is there than that? But Platina is off in another direction away from heaven, disregarding Fr. Seraphim's warnings, and accepting false elders and pseudo-saints. They lack the ability to discern the Church, or else, if they had this discernment, then they would know that ROCOR is the Church (along with the other jurisdictions in communion with ROCOR).
