With reference to the above question, it is particularly instructive to recall the answer once given to an inquirer by the Blessed Theophan the Recluse. The blessed one replied more or less thus: “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.”
We believe the foregoing answer by the saintly ascetic to be the best that can be given in this matter.
* The Greek word for “heresy” is derived from the word for “choice” and hence inherently implies conscious, willful rejection or opposition to the Divine Truth manifest in the Orthodox Church.
