You seem to be wanting to make the point that one can be a Christian without an established form of worship shared by others (a religion). However, this goes contrary to Scriptures... contrary to words Jesus himself, and later other inspired Bible writers, proclaimed.

For example, on the night before he died in prayer to his heavenly father, Jesus made a fervent request pertaining to the importance of unity of his disciples:

John 17:20,21 "I make request, not concerning these only, but also concerning those putting faith in me through their word; in order that they may all be one, just as you, Father, are in union with me and I am in union with you, that they also may be in union with us, in order that the world may believe that you sent me forth"

Also, Paul's words at 1 Corinthians 1:10: "Now I exhort YOU, brothers, through the name of our Lord Jesus Christ that YOU should all speak in agreement, and that there should not be divisions among YOU, but that YOU may be fitly united in the same mind and in the same line of thought.

Unity in worship is a rare thing indeed amongst today's churches... even those of the supposedly same denomination. Yet, how were Christians supposed to carry on doing God's will if they weren't united?

Matthew 28:19, 20: "Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, teaching them to observe all the things I have commanded YOU. And, look! I am with YOU all the days until the conclusion of the system of things."

And once new disciples were made, how were Christians supposed to help one another and encourage one another to be faithful and the doing of fine works if there wasn't a united religion (or unity in worship)?

Heb 10:24,25 "And let us consider one another to incite to love and fine works, not forsaking the gathering of ourselves together, as some have the custom, but encouraging one another, and all the more so as YOU behold the day drawing near."

Therefore, the Bible teaches that those who would follow Jesus in truth would be a united worldwide organization (or religion; ie, form of worship) modeled after that of the first-century Christians. There can only be one true faith. (Ephesians chapter 4)

How would you recognize them?
Matt 7:20 "Really, then, by their fruits YOU will recognize those [men]."... as an organization, they would stand out.
