When there were no stores open to be filled with shoppers on Sunday mornings. But things have changed. People have a lot of choices now on Sunday mornings. Old fashioned hymns aren't familiar to as many people. The stately liturgies confuse visitors instead of drawing them into worship.
Some people dress up, some people dress down.
Some people come to hear the music or the message, some come to soothe their souls, some come to be nourished by the Lord's supper, and some come for all of the above reasons. The need is still to hear the good news of Jesus Christ. People still need to hear that God loves them - God loves you. God loves you. Even if you feel unlovable.
