For those who would malign my posts, know that they are directed as much at Orthodox (myself and others).
You ask, will the heterodox be saved… Why do you worry about them? They have a Saviour Who desires the salvation of every human being. He will take care of them. You and I should not be burdened with such a concern. Study yourself and your own sins… I will tell you one thing, however: should you, being Orthodox and possessing the Truth in its fullness, betray Orthodoxy, and enter a different faith, you will lose your soul forever.
