Ok; why?

You listed three - WHY are they so SACRED?

Because we have been commanded to hold them sacred, and we accepted it by covenant. (which should be reason enough.)

Since I know you will not consider that a good enough answer, the way the endowment for example is presented reveals truths that are eternal, I have had many an epiphany while in an endowment session on some point of doctrine which in prior sessions had not occurred to me for I was not ready, this communion with God and fluidity of knowledge from the spirit, I personally hold sacred, as many of my catholic friends hold their rosary sacred.

Let us use that as an example, say I a non-Catholic bought a rosary, not to pray over, but for my daughter to use in her dress up box, I allowed her to take them outside and play with them getting them muddy and allowing them to be stepped on and abused as toys often are. Would a neighbor who was Catholic be offended? I think they would. If I bought a priests collar to use at a drunken party, or a habit to use at an orgy, or a Jewish prayer shawl to wear to a skin head party. There are things that just ought not to be done, ceremonies that mean so much to those who believe in them should be treated with the same respect that you would treat that person, maybe even more respect. To disrespect the trappings of any religion is disrespectful to them and more disrespectful to the person "Disrespecting" the religion for it shows that the disrespecter has no mercy, Which is the best thing to be found possessed of at the last day.

Lastly, if someone is crass enough to be disrespectful of another persons heartfelt beliefs, they can expect, human nature being what it is, that the person who has been attacked in this most personal manner, will retaliate in kind Thus, they will have started a conflict. Jesus taught men to love their enemies, do good to them who despitefully use you, and to turn the other cheek. this is incompatible with the attitude of "I attack because I can", which reminds me more of Bill and Hillary and the liberals.

I have at times engaged in such behavior myself. It is something I regret when the heat of the moment is over and I stand, surveying the damage I have wrought. Luckily, for me, I can still repent of such behavior, and try to rid myself of the attitudes that bring it out, when I feel attacked.

I hope I have answered your questions about both sacredness, and respect.

May God bless you and heal the wounds that abide in all our hearts, may you awaken tomorrow full of the joy of a soul refreshed by our saviors love, amen.

By Whom??

Since I know you will not consider that a good enough answer...

It's not that it's not GOOD enough, it's that it fails to address what was questioned!

It's beginning to look as though you folks are not supposed to tell what goes on there, but are 'commanded' (by someone) to remain silent on WHY you are to remain silent!

Lastly, if someone is crass enough to be disrespectful of another persons heartfelt beliefs,

So in your mind, you equate an outsiders request to know WHY you do certain things to DISRESPECTFUL??

I hope I have answered your questions about both sacredness, and respect.

No; you haven't answered and you've tried to make ME the bad guy for asking.

Why is that?
