Hello my friend!
Honestly, I had never heard the english word. I knew it in Greek, but not in English. But I searched for it, and I found two interesting links about Toll Houses:
To say a few words, just as Fr. Thomas Hopko mentions, it is a very classical, traditional, orthodox, allegorical teaching that began to be too literalistically interpreted, and therefore got deviated in various ways.
To close my reply, I would like to admit that I am not an Orthodox theologian. Eschatology is a part that I haven’t study much (yet) so please feel free to ask your question at AskOrthodox, and you will receive a much more convenient answer.
Thank you very much!
God bless you always!
