It's hard to take anything by St. John of Kronstadt seriously when he defrauded his wife from sex intentionally.What is your basis for this? Everything I have read said it was a mutual decision. Of course, I suspect most Orthodox sources would not say "St. John of Kronstadt was a great guy except for defrauding his wife"
My basis? Ask Father G if he still posts here.
He intentionally refused to consumate the marriage to his wife. She couldn't even divorce him and actually was counselled to stay with him.
He deceived her, whereas she had no intention the marriage wouldn't be physical.
