As suggested by here, some good words to keep front and center in this time of preparation:
I understand that you are on the way to becoming Orthodox. I know nothing about you, beyond the fact that you are English.
Before we go any further, there is one point I should make clear. I have not been told why you are about to convert, but I assure you there is no point whatsoever if it is for negative reasons. You will find as much “wrong” (if not more) in Orthodoxy as in the Anglican or Roman Churches.
Are you expecting a kind of earthly paradise with plenty of incense and the right kind of music?
Do you expect to go straight to heaven if you cross yourself slowly, pompously and in the correct form from the right side?
Have you read the Gospels?
Have you faced Christ crucified? In the spirit have you attended the Last Supper – the meaning of Holy Communion?
Are you prepared, in all humility, to understand that you will never, in this life, know beyond Faith; that Faith means accepting the Truth without proof. Faith and knowledge are the ultimate contradiction –and the ultimate absorption into each other.
