For me it contains quite a bit of spiritual merit. My scriptures have a line "As thou deemest thyself, so deem others." There are very similar verses in Jewish and Christian scriptures.
That to me is not something to read and nod in agreement, it is something to be lived at the behest of the Almighty God. This is not a mere suggestion...it is something to be fulfilled.
While I am not qualified to interpret Judeo-Christian scripture...I can't help but notice the importance (and please forgive me if I am misquoting): Do unto others as you would have them do unto you. Christians call that the Golden Rule.
Jewish scripture calls the same line the First Mitzvah and says: Do unto others as you would have them do unto you. That is the entire law, the rest is commentary.
The golden rule. The entire law. To me, those are powerful words.
While I can't tell anyone how to live by their scriptures...and I certainly do not want to be the judge of who is a good religious person and who is not...respect to me is something that is very spiritual.
If one had respect for another, would one cheat another? Lie to another? Steal from another? Harm another in any way?
Respect is so strong, for it not only can bring out the good in another person...but it can also be vigorous, enough to bring out the good in us, sometimes while silencing the darker parts of ourselves in the process. It is through respect that we can voluntarily and delightedly see the benefits of living the other values in our belief system.
It's a powerful quality....and one that must be lived.
(in my opinion, anyway)
