There are wars going on around the world, people are starving and Christians are being systematically slaughtered in Iraq, but God is more concerned about what a person wears to church. Armstrongism's god certainly has better things to worry about. Those people are going to die anyway because they are "false" Christians. Besides, God is only concerned about those few hundred people in a little splinter cult who claims to be the "true church."
Weinlands's god is so concerned about his "true" men that he does not want them wearing their jackets when it is 70 degrees or higher.
This brings us back to addressing how we come before God on the Sabbath. If we are in the privacy of our own home, perhaps with even a handful of people joining us for Sabbath services, it is not good to go into a private home “over-dressed.” Again, this is about a balanced and moderate example we are seeking to set for our neighbors. So there is a “balance” in this. We should not “dress-down” either, as with wearing blue jeans and a t-shirt, or other exceptionally casual clothing. In such instances, nicer casual clothing is fine and proper to be worn before God in such a meeting location. However, a suit and tie for a man or a dress or pant suit for a woman can be too much for such a private home meeting. In a “more formal gathering” of a special meeting location for the Sabbath, such as a hotel meeting room or other rental location, a suit (or sports jacket) and tie for a man is proper, as is a dress or type of dress suit (nicer dress pants and blouse) is proper for a woman.
The exception to this formal attire for a more formal gathering (not at a persons home) on the Sabbath is when temperatures outside are reaching the mid 70′s (Fahrenheit) or around 23 degrees Celsius and above. At such times, jackets need not be worn at all on the Sabbath. This also includes wearing a tie. There is no requirement for a tie on the Sabbath when temperatures reach such levels. The physical body does not function well under such conditions and at such times less will be able to be gleaned from sermons when people are so uncomfortable. It is far more important that we receive all the spiritual food we potentially can on a Sabbath without such encumbrances.
