That is correct. As long as He is in your heart, it doesn't matter where you are.
Oh, good grief.
I don't have to physically be in a church to worship God or to celebrate the birth of Christ.
Of course one doesn't have to be in a church, but if a believer wants to join with other believers (within the body)it makes sense to do this in a bible believing/teaching church. We are called to come together regularly to worship God together corporately. It is biblical.
