I make no distinction between the body and its head. If I shoot you in the body, am I not also trying to destroy your whole body, your head included?
If you attack the body you attack its head also.
A Secret Service agent does not simply put his body between an assassin and his bullet if the assassin only aims at the president's knee. Shooting at any part of the body will cause the Secret Service agent to give his life for his president.
Likewise, in fighting for my Church, the body of Christ, I fight for its Head, Jesus Christ. If I must lay down my life for my Church, I am, in reality, laying down my life for its Head, Jesus Christ.
I do not agree with your false distinction between the two. Likewise, if you attack the body, the RCC, you also attack the Head, Jesus Christ. You cannot attack the RCC in its teachings on faith and morals without also attacking Christ. Therefore, to be logical I must conclude that such attacks are demonic, inspired by the one who is anti Christ, Satan.
The bible tells us that he will come in sheeps clothing and that if possible even the elect could be deceived.
So do not spend so much time looking for the enemies of Christ look for those that steal His authority and position
