Let’s see what Jesus had to say about it:
Mark 7:9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
Mark 7:10 For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
Mark 7:11 But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
Mark 7:12 And ye suffer him no more to do ought for his father or his mother;
Mark 7:13 Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
The pharisees had developed a FALSE tradition that if you declared all your property “Corban” – i.e. a gift dedicated to the church, you wouldn’t have to take care of your parents. You could simply say, “Sorry Pops, no can do, all my money belongs to Jesus”.
Thus the pharisees were able to ignore the 5th commandment, “Honour thy father and thy mother“. And just in case somebody of the Catholic persuasion should be reading this, yes it is the 5th commandment and not the 4th.
Jesus proceeded to give the pharisees a powerful rebuke: ALL Ten Commandments – including the 5th – are still America’s Moral Foundation. If your son gives you lip, you’re authorized and mandated to kill him. As Jesus puts it, “Whoso curseth father or mother, let him die the death“.
So to answer the original question.
For children it means that even if you bequeath your entire estate to Landover, you and not Landover shall be responsible for looking after your doting parents. Jesus won’t be responsible for your parents until after they are dead.
For parents it means that you are still allowed to kill your unruly children, no matter how old they are (Please note, that Jesus’ words may have been made of none effect through local, secular legislation. Also note that Landover does not as a rule endorse the killing of people, who have testated their property to Landover. Jesus has lots of time (Psalm 90:4, 2 Peter 3:8).
