Elder Athanasius will be canonised by the Patriarchate in coming years because of his amazing theological insight ... he is not just an interpretor but a creator of insight into the Scriptures - hence, why I get excited often and love to post according to the things I have heard him say.
He explains in detail the door based on the Greek text of the Noah story ... I dont think its hard to understand the point he makes in that to enter into the ark (the church) there is only ONE door .. not two or three. This single door is baptism.
Vasiliki - do you know if this explanation by Elder Athanasius is in any books (whether written by him or by someone else)? I would love to read the full version myself. I know you mentioned listening to it on tape, but I absorb things much better by reading than by listening, so I was hoping to find a written version. I thought about PM-ing you but posted instead since I thought this might be of interest to others also.
