The "4" are not seeking clarification .  They have played their hand brazenly .  They demand that Francis admit he is wrong .  And should he not say those words they will "correct " him !  
It's their way or the highway ...  Francis must guard the gullible from the wolf  .  He has no need to protect himself .  
This is a power play by the "4" for the "4" .  God , his Christ and the work of salvation mean very little or nothing to them .
