3) You should always turn the other cheek if someone wishes to harm you unless to do so causes a greater harm. You also have an obligation to increase good and decrease evil. This may require other action: it should be done with skill and wisdom, and great carefulness, involving the least possible force or violence. But if someone wishes to harm you, know they have first harmed themselves and any response, no matter whether with force or not, should be done with compasssion. I believe the Church teaching on Just War is very wise and well structured.
4)Our culture (and many others) focus on material gain, or rather values material above other things - true. This value scale is false. It is a false allocation of value that can be demonstrated and taught as certainly as it can be shown that happiness is more valuable than unhappiness. I hope to be one who helps others learn what is of true value.
It helped me to be poor and happy and rich and miserable. Others may need other examples or instruction. It is not poverty or wealth that is the point of the teaching, but what you value and how those values are reflected in your dealings with God and your fellow creatures in this life.
