We ARE one body in Christ. Denominations did not exist in the early church and whenever someone was tying to start up a new sect/denomination (Cephus, Apollus, etc) the Apostle Paul refuted them and in so many words ordered them to cease and desist.
So as long as you are saved in Christ any Christian church SHOULD welcome and accept you, unfortunately they do not, at least once they discover that you are not LIKE them.
It is wise, as another has said, to get or search an objective source for denominational doctrine. I have bought and used one, "Handbook of Denominations" is what I believe it is called and it is very objective and has been a good resource for me. Mine is a blue w/gold lettering, hardbound book. I am sure that there must have been several updated versions since I bought it. ALSO, and maybe better is to go to its web site and search there under tabs such as "About Us," or "What We Believe," or "Our Church/Denominational Doctrine." There you should also be able to find out what Denomination, if any, to which it belongs. Non-Denominational churches usually give you a pretty good idea in what they offer online. If a church has no web site in this age then it probably thinks that the internet is all evil or it is a church with exclusively computer illiterate people, all over 90? We, not just missionaries, have been told to go unto all the world and preach the Gospel and the www IS the most efficient/economical way to go.
My wife and I have had to wander/meander several towns for a church family. If you are looking to select a church for membership and get involved and serve, I strongly suggest ONE church at a time. There is just too much you need to discover. You MUST NOT assume anything or even believe what you are told. Everything needs to be certified by you guys. There is not one person in any church who is perfect, NONE are, just like myself and you. To find a church family requires time of regular attendance 2 or 3 times every week or more for a period of 3-6 mos, at least that is what it takes for my wife and I. And then you may have to start all over and over. It is VERY, VERY HARD work for us and can be discouraging. But in time if you persevere you will be rewarded. But if you are just looking for different pews to keep warm and then quickly depart, anything will do, esp. if you bring tithes and offerings.
May the Lord bless your venturing. Research each church first. If they make needed information HARD to find or get or just not available, I must assume in this day and age that they are trying to hide something. I believe that you can get a web page for free and certainly someone in the church should have the ability and basic knowledge to fill out the pre-formated web page(s.)
