That would not cause everybody to have the same interpretation,because if they rejected Christ and what He said while on earth,especially when Christ said the miracles that He does testifies that He is the Christ,many people would reject that person,and say he is not from God.
The only way all people would believe in the same interpretation,is if God took upon Himself a human body,and forced everybody to abide by the same interpretation,or else pay the consequence there and then.
That will not happen because however Jesus showed love when He was on earth,is the same love that applies now,and as long as we are under grace,and to not fight physically for the kingdom of God,but must be done in a peaceful manner,and not force,then everybody will not have the same interpretation.
The only way everybody will have the same interpretation is if it is a fear factor that they cannot deny if they do not obey that interpretation,which the Roman Catholic Church tried,but people could escape the Roman Catholic Church,but if God were on earth forcing people to obey people could not escape that,but God will not do that so everybody will not have the same interpretation.
Even some people of the Roman Catholic Church,in which the Pope claims to be head of the Church,does not agree with everything he says.
