gratitude towards & repaying the debt to one's parents Consider these two texts:


https://www.accesstoinsight.org/tipitaka/kn/iti/iti.4.100-112.than.html
the part that contains:


  Mother &amp; father,
  compassionate to their family,
  are called
  Brahma,
  first teachers,
  those worthy of gifts
  from their children.
  So the wise should pay them
          homage,
          honor
      with food &amp; drink
      clothing &amp; bedding
      anointing &amp; bathing
      &amp; washing their feet.
  Performing these services to their parents,
  the wise
      are praised right here
      and after death
      rejoice in heaven.

  But anyone who rouses his unbelieving mother &amp; father, settles &amp; establishes them in conviction; rouses his unvirtuous mother &amp; father, settles &amp; establishes them in virtue; rouses his stingy mother &amp; father, settles &amp; establishes them in generosity; rouses his foolish mother &amp; father, settles &amp; establishes them in discernment: To this extent one pays &amp; repays one's mother &amp; father.



What is are the appropriate ways to combine the meaning/purpose of these, considering that there is some potential to misunderstand the way these two guide us to treat our parents?
Combining these 2:: 
There are lot of if-else cases here, might not be able to cover them up. 

Understand from below scenario. 

I am a well grown up person, a householder. Living independently, standing on my own foot. Either I regularly pay visit to oldies or live with them. I take care of them although they are stingy, fool, unvirtuous etc. in terms of dhamma or might be physically as well. I respect them, wash them, provide them food, clothing, medicines, etc. 

I also try to change their views, try to establish them in dhamma by myself trying to walk on Noble path of householder under dhamma. 

Another Scenario:: 
Parents are enjoying their oldage in their own way, they have enough financial &amp; physical support other than me. Either they don't want to see me or yes we have still good relation. 
In this case, I am also living independently, living my householder life under dhamma. Here,  I maintain compassion in mind towards them &amp; gives metta so as they would also take homage to buddha &amp; his dhamma. 

As a homeless or as a monk:: 
I am living my peaceful life and never turns back from my parents, if they are against me &amp; want to kill me for I joined Buddhism, who cares? Death is certain? If they are not against me, it's good. Whatever the case is, I maintain compassion for the body I received from them. This compassion here acts as mental-vibrant-food for them and also as blessings for them. I am ready to accept them in Sangha, if they are ready to follow stated percepts. 

Whatever the case is, I am not running away from maintaining compassion. I am not running away from the duties. I am not doing it to get something in return but by understanding as to how difficult it is for a parent to give out a new body. 

This doesn't mean that I support their wrong view of buddhism or of dhamma. In terms of dhamma &amp; sila in life, I am still determined &amp; strong.
