I was at home yesterday, and I came up with a pretty good analogy.

New York City is New York City. Nothing more, nothing less. Whether you get there by train, car, bust, taxi, or boat, it's still the city. You can drive there so many ways: up from New Jersey, south from the suburbs, or west from Long Island. Sure, some roads are more dangerous than others, but as long as you drive safely, you have little reason to worry. And if you stop to get gas or eat, who cares? It doesn't matter as long as you get back on the road when you're done. Any way you go, you're still ending up in New York City.

What I'm trying to say is that there's no one true way to practice religion. In the end, provided you're not overzealous or corrupt and try to twist your beliefs, pretty much each path ultimately requires good actions. Everyone is allowed to deviate a little and differ in their approach, because the results are the same.
