Even the term Protestant is a label. It means the people who protested against the practices of the existing church, as outlined by Martin Luther, who posted his protests on a church door in the 16th Century.
The only time a pure Christian church existed was when Jesus spoke. Since then, people have been doing their best, with mixed success, to follow Him. And since He is the only perfect person to have ever existed, it's to be expected that the rest of us fall short, in spite of our best intentions.
No, modern Christians will never never be able to create a pure church. And there will always be people protesting about those impurities. But the spirit of the Puritans returns each time you seek to follow Him more nearly. If people scoff at you, and poke fun, don't worry about it. It wouldn't be the first time.
