"Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you." - Ephesians 4:30-32
"Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality, heresies, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God." - Galatians 5:19-21
Exactly - anyone who has outbursts of anger when reading TRUTH is acting in the flesh. And using manipulative words to defend their man made tradition which IS of the flesh.
The RCC grieves the HOLY SPIRIT simply by it’s existence with it’s man made doctrine/tradition of infallibility. Anyone with the Holy Spirit within them shuns them/their teachings.
