Just to provide some perspective...
Orthodox Christianity teaches that, after this life is over, God will bathe
all humans in the light of his love with absolutely no discrimination and no cruelty. This experience will be bliss for those who would prefer to be transfigured by this love and will be painful for those who would prefer to retain their malice, ignorance, and selfishness.
We can imagine that some people who have currently
rejected a belief in the Trinity will nevertheless experience the love of God as bliss. We can also imagine that some people who have
defended a belief in the Trinity will nevertheless experience the love of God as painful. (Such will be the case, for example, for John Calvin should he
refuse to repent for his treatment of Michael Servetus.)
We can also imagine that
everybody will experience the love of God as bliss (
apokatastasis ton panton), and that
everybody will experience the love of God as painful (this is my own personal prediction).
Thus, Orthodox Christians do not believe in "hell" as Protestants use this word (the idea of God glorifying himself by rendering infinite penalties upon non-believing sinners).
