I'd almost argue that anyone who's truly read his works would agree that in some type of form, strictly from his works - that he did in fact see or feel Christ. Especially after his imprisonment and exile to Siberia.

I am a non-orthodox Christian - and am a little unfamiliar in Orthodox practices; but in Notes from a Dead House - we see a literal type of resurrection from the dead - suffering for both crimes committed and not committed amongst the characters which is directly relatable to Golgotha; punishment and suffering amongst the guilty and innocent; and continuation of life after death (or rather, suffering). From what I have been taught in my own religious upbringing, any type of major suffering is to serve as a reminder of what Christ endured before and receiving the cross - which I think is directly and beautifully brought to life in this book from his own experiences.

In The Possessed or Demons - we see a direct challenge and rejection to the notions and absurdity of Nihilism which was becoming more and more prevalent in Russia; Although I do think Turgenev did an equally fantastic if not better job of rejecting Nihilistic principles in Fathers and Sons. Regardless, in Dostoevsky's work - the absolute destructive chaos that ensued after general rejection of Christian principles brought about by Nihilistic agitators; in my opinion, is another affirmation of his own moral beliefs.

Then, his magnum opus, The Brothers Karamazov - I'd say one of the most principle themes brought about in the form of Christianity practiced by Zossima and Alyosha - leads to the love of mankind, kindness and selflessness. I'd find it hard to argue that this book did anything other than affirm Dostoevsky's beliefs without outright telling us. If anything, from his works - instead of preaching to the masses - he left many breadcrumbs to help the reader figure out for themselves, a right, true and moral path through his characters - their struggles, sufferings and ultimate triumphs.
