Yes, definetely, a christian is simply one who has trusted in what Jesus did on the cross to pay for his sins is true and accepted the free gift. Most denominations believe the fundamentals, i.e. the blood atonement, virgin birth, deity of Christ, His bodily death and resurrection, and His second coming, although there are some differences on other more minor issues. Of course the love and vibrance of the folks is important, but, doctrine, how do their teachings line up with the word of God, is very important when choosing a church. Don't fall into the error of, well, their music is really cool although some of the things they do don't seem to fit what the Bible says quite right. Be sure they teach sound doctrine, and study for yourself to be sure you know what you believe is sound doctrine and find a church that is in line with that. I personaly have felt quite at home in many different churches that would be called main-line denominations, like baptist, methodist, lutheran, presbyterian, etc., or non-denomination or a 'grace', or 'community church', or whatever they want to call themselves, or if they have a traditional or contemporary style worship service. If they lift up Jesus and teach salvation by grace, (undeserved favor and pardon given freely to all who would ask), you should be ok. Just be sure you know your Bible and use that to test their teachings. Ya don't wanna end up in a David Koresh cult or some other weird 'fringe' movement. Hope that helps some.
