Who has it right?

I have been wondering which church has it right.  You know the whole worship thing.  Does any one particular church have the right music?  or the right building?  or how about the right way to baptize?  Some churches baptize babies while others say that is completely wrong...so who is right? I never understood the animosity some denominations have for others.  Growing up in the south was a different experience for this girl who grew up a Lutheran.  The baptists in the area didn't agree with what we were taught and on occasion let us know when they stopped by the house to invite us to church.     This blog isn't meant to bash baptists just an observation of how each church sees others.  Isn't the whole point of church to worship God with other believers?  To praise our Heavenly father?  When did it become a competition to see who can get the most people saved?  You would think churches would be happy to see other denominations thriving if it meant they were bringing people to the Lord but it just doesn't seem that way to me.  If you don't do "church" their way you are doing it wrong.  If you don't pray right or sing the right songs or have an alter call you just are doing it wrong.   But who decides what is right and wrong?  I was always taught if a church is teaching biblical principles it is a good church but with so many ways the bible is interpreted who gets to decide what is biblical?  One church speaks in tongues while others don't.  One has alter calls and not the other. There even those that think handling poisonous snakes is biblical......so who is right? I don't think anyone can answer that question and I guess we won't know until we get to heaven.  Can you imagine walking up to Jesus in heaven and asking him which church had it right? I imagine he will have a great answer.
