A Question of Clothing?--Not Really

Intro to this post here.
 
Question 1: What is the doctrine (eternal why) behind the non-casual dress standard?  Who decided what the non-casual dress standard is?  How Come?

"I'm sure our Samoan brethren hope we never have a rule against deacons wearing skirts," Bishop Robert L. Simpson told the assembled General Conference attendees in 1970. "Our objective [regarding Sunday dress]," he continued, "should be grooming appropriate to the area and in all cases cleanliness."

"Anything that symbolizes either rebellion," he continued, "or nonconformity to the local community standard will likely be a distraction to those partaking of the Lord's Supper. Conservative dress and manner have always been the keynote of priesthood service. If there is a probability that the members you serve are thinking more about your non-standard appearance than about the atoning sacrifice of the Savior, then you had better take a long, hard look at yourself before next Sunday."

          That counsel was reiterated in our day.

          “How we dress,” Elder Oaks says a few years ago, “is an important indicator of our attitude and preparation for any activity in which we will engage. If we are going swimming or hiking or playing on the beach, our clothing, including our footwear, will indicate this. The same should be true of how we dress when we are to participate in the ordinance of the sacrament. It is like going to the temple. Our manner of dress indicates the degree to which we understand and honor the ordinance in which we will participate.”

          Why white shirts when passing the sacrament?

          Elder Holland reminds us: ““For sacred ordinances in the Church we often use ceremonial clothing, and a white shirt could be seen as a gentle reminder of the white clothing you wore in the baptismal font and an anticipation of the white shirt you will soon wear into the temple and onto your missions” (“This Do in Remembrance of Me,” Ensign, Nov. 1995, 68).

 Satan is a master Illusionist...he can't hide truth under a basket because truth, like the sun, permeates everything...but that doesn't matter if he can distract our attention...which he does

The sacrament is the ordinance in which we renew our covenant...and in turn the covenant renews us...what power!  But if we are too focused on the culture having such an uncomfortable dress standard then we will miss out on what Pres. Hinckley described as "an ordinance without peer."

And that would be very sad.
