The Family Inclusion Principle in John's Gospel

Jesus directly disrupts the family inclusion principle in two ways. In chapter 10, he does it by showing that the gospel disrupts families and in chapter 12, shows that the gospel forms true families. A fourth argument in support of the fact that this principle is abrogated can be drawn from John's gospel. There's no way in John's gospel to see this principle carried through when there is contrast drawn between flesh and spirit.
