I've only been in one Baptist Church and I don't remember see of the Icons or Images we have in the Catholic Church. Can any Baptists out there enlighten as to the trappings of a typical Baptists Church?
Funny, I had to go to a non Catholic Church for Easter one year with some friends and I was so nervous (I even went to Mass the night before so I settled the Sunday Obligation). I was so afraid of what was going to go on and happen to me. It was actually quite nice and had almost all the elements of the Catholic Church but a bit different. I still feel ridiculous for having those feelings after all these years.
They are decorated simply, like most Protestant churches, although they do allow images and there will be a cross. The main difference you would notice is they will have a large tank for baptism by immersion, although it can be concealed when it's not in use.
Typically just a "bare" cross - and perhaps a stained glass window or two depicting Bibical events
A bptist church may or may not have stained glass windows...some stained glass windows may have Biblical images in some churches; others just multicolored glass. A lot of Baptismals in Baptist churches may have artist representations painted on their backwalls of the River Jordan with Jesus in the River with John the Baptist...or other pastoral scenes or even resentations of the Holy Spirit in the shape of a Dove alighting on Jesus' head.
A Baptist Church often has a central pulpit with a table in front of it used to receive the offerings or to support the wine and bread trays when the Eucharist(or Lord's Supper as Baptists call it) is being celebrated. Some times these tables may have a Large Bible opened to some relavent passage. Baptist churches might often have an American flag and a Christian flag in the front corners as well. Many Baptist churches may have plaques on their sanctuary walls with removable numbers and letters which announce the attendance and offering statistics from the week before.
Smaller churches of course tend to be sparser and more utilitarian in their decor...larger more formal Baptist sanctuaries can approach the artistic complexities of their Catholic and High Protestant cousins....buildings built in the 1980's thru the present will feature open, spacious designs with every kind of audio video feature and the latest in lighting/controls. (Dolby 5.1 surround any-one? I know, I redesigned such a sanctuary's sound system, adding video as well!)
