We should apply those principles to everyone anyway, Christian or not
because we are suppose to love each other as Jesus told us to do. We cant just judge that is not our job, we should all try to get along.
Practice each of the 6 principles allows you to recognize the humanity in all religions. We are all humans who have differing beliefs and reminding yourself to be genuine, respectful, humble, fair, discerning, and discreet allows space for trust to grow among contrasting religions
The “Six Principles of Relationship” are genuine, respectful, humble, fair, discerning, and discreet. They are essential because when Jesus said in Mathew 22:39, to love our neighbors as ourselves, He was not referring to people of the same faith only. Therefore, we need the six principles to guide us in our relationship with people of different religious beliefs.
So we can get along well with other people
