Mk 7:12 ... "(Then) you no longer let him do anything for his father or mother, ..."

Verse 12 has one phrase containing these 10 dialog words ... ouketi afiete auton ouden poiēsai tiō patri ē tiē mētri [(Then) "No longer do you permit him anything to do for the father or the mother")].

This is the "then" part of the argument. The diagram shows the father and mother cut off from the gift of their son. This means the parents get nothing.
