The phrase "There is no salvation outside the Church" and "Those outside the Church will perish like Noah" seems to very logically and intrinsically suggest a type of Feeneyism where all heretics, infidels, etc. will burn forever.
For the longest while I had no problem with this, because - quite disgustingly, as I am a disgusting person - I was quite more of a Pharisee than I am now, and I simply used Orthodoxy not as a means of discipline and self-betterment, but as nothing more than a proxy of intentionally and childishly abdicating the faults of who I was, and be able to have an upper ground of judgment on the rest of the world.
You can't tell me that this phraseology doesn't have such a logical implication of the whole non-Orthodox world being condemned. I tried using said phraseology in the most charitable way possible when discussing this topic when it came up with Orthodoxy with my Catholic family (how there's no Salvation Outside the Church, but we don't know who's saved and who's not, it's possible that they can be saved before the Last Judgment, God will judge everyone with perfect justice), and now my family occasionally torments me about how I think my dead, really loving and devout Protestant grandparents are burning in Hell, because they don't rely on academic dialectic to try to synthesize contradictory ideas; rather, they are simple people who hear what's being said and understand what's being said alone and in of itself.
But their opinions are not what's bothering me - such an idea has bothered me ever since I realized how I was blaspheming Orthodoxy with who I was, because I now realize how unjust it seems to be, when it seems that Orthodoxy should be understood as nothing more but a means of personal transfiguration through Christ and a love of the human dignity that each person deserves, and repentance through God's Grace and ultimately, Union with God - but there are and were clearly other paths which offered this same methodology and end-goal, whether it's Traditional Catholicism and the writings of the Carmelites, Old Believers, Oriental Orthodoxy, etc.
When all of them have extremely similar methodology and produce holy people who act similarly to each other (Francis of Assisi and Basil of Moscow, Padre Pio and Paisios the Athonite, Maximilian Kolbe and Dimitri Klepinin),
it's frustrating that the doctrine implies a basic guessing game - a very cruel and agonizing when, especially when there are Catholics who put most lukewarm and lazy Orthodox to absolute shame.

Oops, these Priests are condemned to hell, they were schismatic heretics. I'm sorry man.
