Mankind always thinks it can make up rules to help God monitor His people. When we look at the mentality behind making unbiblical rules, we see that these rules are based on man's desire to be superior to others.
We don't need to make our own rules to make sure people will obey the Bible; those who are controlled by the Holy Spirit will be what they should be because of the Holy Spirit who lives in them. Man's rules are never helpful or better than God's Word.
Galatians 5:22-23
"22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law."
When the Holy Spirit lives in us we need no extra laws God never gave to intimidate people into making sure they are "doing just right."
I was once told by Christians that it was a sin to drink coffee because it was a stimulant. Since I saw no command in scripture that told me this, I dismissed it as foolishness, since food is a stimulant, we have more energy when we eat it than if we didn't eat it. Some things just get silly when people make rules God never made and intimidate others into following their rules.
A Christian woman once gave me a bottle of apple juice that was a gift to her. I asked her why she didn't want it, and she told me it was because the bottle looked like a wine bottle and she was concerned that anyone seeing it would think that she drinks wine. I thanked her for the juice and gladly drank it.
The scripture that was used to justify this thinking was that we are to "avoid the appearance of evil." As I pondered this, it occurred to me that she didn't mind giving that "appearance of evil" to another believer but was fearful of her own reputation. I felt a little sad for her because what a burden it would be to have to continually worry about "appearances" when we are not doing anything wrong.
Superficial Christians are often more worried about how they appear than the substance of their character. If we are not doing anything wrong and someone else judges it, then that is on that other person who judges, not on us.
When I went back to the scripture and studied further, I realized the verse should have been translated, "avoid evil," rather than anything having to do with appearances.
Christ was judged by appearances when He ate and drank with sinners. Should He have avoided sinners to avoid being judged? His mission was to bring the gospel to them.
If we had to continually worry about how others are judging us, we wouldn't be seen in public at all, since everything could be judged as bad by those who are self-righteous, looking for things to monitor in others.
There are many people who will choose to judge innocent matters because of their angst toward us.
One Saturday, many years ago, my husband and I wanted to go to a flea market. The parking lot of the market was full, so we had to go across the street to the closed tavern. Our car was the only car in that lot when we arrived. We parked and walked across the street to the market.
A few days later, we were at a family gathering, and a relative loudly proclaimed that my husband and I were at the bar on a Saturday morning, drinking. We don't go to bars, but because we were known to be Christians, this person wanted to "expose" us by tattling on us. It was quite amusing because we explained to the people in the room that the bar was closed, we parked there to go to the flea market across the street, and she looked silly for her tattling.
Should we not have parked in that lot for fear of how it would look? No, we cannot worry about every little thing that we do that may be misinterpreted by onlookers.
It has been my experience that if someone doesn't like you, they will deliberately misinterpret what you do because their desire is to harm you in some way.
This is what the devil did in the garden with Eve. He smeared the reputation of God because of his hatred toward God. He wanted Eve to think mean things about God so that she would turn on Him and follow the devil, the one who gossiped and lied.
I have even heard people judge a person wearing torn jeans to a Christian gathering, being judged for it, and even a man wearing a suit judged for it because he was said to be too concerned about clothing style. Here's the thing: why would we see the man wearing the suit as being too concerned about clothing, but not the man in the torn jeans as too concerned about clothing?
One man once said he thought the old timers were too worried about dressing up for church, so he dressed down because he liked it. It is possible that the young man was the one too concerned about clothing, or he wouldn't even mention it.
I don't notice clothing much when in a gathering, unless it is immoral and distracting. I do think clothing style can reflect disrespect for others. I do have to ask why someone would come to a gathering in a tank top and jeans but go to the office Christmas party dressed to the nines. Just saying!
Perhaps if someone does have decent clothing, they should choose that over the clothes they wear when they mow the grass, merely out of respect for the others.
The only passage I see in Scripture about the Christian gathering was that no one should be treated better because of their financial status, which was reflected in their clothing. In other words, we are not to prefer the wealthy person over the poor person. It didn't have to do with clothing; it had to do with highly valuing someone or devaluing them based on their wealth.
James 2:2-4 "2 For if a man comes into your assembly with a gold ring and is dressed in bright clothes, and a poor man in dirty clothes also comes in,
3 and you pay special attention to the one who is wearing the bright clothes, and say, “You sit here in a good place,” and you say to the poor man, “You stand over there, or sit down by my footstool,”
4 have you not made distinctions among yourselves, and become judges with evil motives? "
We must judge sin, call it out, and attempt to restore the one who has sinned when there is confession and forgiveness extended. But we have no business judging things that God did not clearly state were sins.
