I disagree with you on that. There are certainly bedrock principles and sacraments (communion, for example) that need to remain, but I suspect that few of us would feel comfortable with worship as practiced, for example, in Ephesus in the first century.
Other than the language barrier, what, exactly, do you think would make you uncomfortable in such a primitive Christian setting?
