Yeah reading more into the struggles the USSR had with the orthodox church you're right to say that Stalin 100% ditched this outlook by the 1930s as he was calling for state athiesm in the 1930s and kept trying to purge the 'reactionary' orthdox church members from positions of infulence.

I am wrong to say that the direction of this was because of fears of Stalins orthodoxy, my mistake.

The key thing though to take away was, that he mostly failed; Russia was just that much orthodox. The key points where how he made concessions like recriminalizing abortion in the 1930s; not a position he likely would have wanted to do due to his ideological position, but one he had to do to maintain a cohesive country.
