Oh bother! This one is going around again?
1. What the majority decides, on the beach or off of it, does not make right right. Modesty is not exemplified by bathing suits, no matter what!
2. 1 Tim. 1:17, along with many other verses, tells us that to God is due all glory and honor. It is not wrong to dress up a little for church. It is wrong to show off, but it is just as wrong to pretend church is nothing more than another place to visit no matter what you are wearing.
3. ANYTHING that draws attention to the sexual side of your body is wrong in church. It doesn't matter if it is a skirt, dress, shorts, pants, kilt, whatever. Drawing attention to that side of your body means you are distracting some from worship. That is definitely wrong. (It ain't so right any other time outside of the marriage bedroom, either!)
4. Encouraging others in their time of worship and praise means dressing modestly without pretension. Personally I do have a problem with jeans on girls/women in church, but that is my problem, I think, not theirs. As long as they aren't skin-tight or super low-cuts, my problem is simply that: my problem.
5. Fashions change. Honor and respect for God and others do not.
P.S. I'm sitting here typing in jeans and a striped t-shirt. And I would bet no one would ever mistake me for anything but an over-40 lady! For me, jeans and a t-shirt are almost like a uniform as I clean house, work in the yard, and deal with the animals and our retarded son's (almost 21 years old) diaper changes!
