Is there some kind of dress code?
Yes. The code is wear some clothes.
Believe it or not, folks in some churches have an issue with what people wear to church.
On the one hand, some folks think a suit & tie or a dress/skirt & blouse should be standard fare. The thinking is,
If we’re required to wear our best when coming before a dignitary or royalty, then we should wear our best before God at church.
This is a very good point.
Another group of folks sees that nice jeans and t-shirts are acceptable (and encouraged!). They see God as a loving Father who accepts them as they are in Christ– forgiven because their clothing is the righteousness of God in Christ.
And this is another very good point.
This is not an either/or issue. It is a both/and issue. We can have people wear suits and ties and others jeans and t-shirts because our God is not one-dimensional.
God’s glory is multi-faceted. He is not only the King of Kings and Lord of Lords before Whom we wear our very best; He is also our Father before Whom our suit coat and tie are not required.
Do we want to present a one-dimensional God or do we want to display the glory of God in his multi-faceted beauty?
The glory of the Gospel is most evidently displayed when we come together as one with the diverse nature of our personalities, hair styles and colors, smiles, and clothing.
So, whether you eat or drink, or whatever you do, do all to the glory of God.
