The OCs (Original Christians) came together to worship God. They did so in secret, deep in the catacombs, the altar often being the tomb of a Christian martyr.
I think it depends on the attitudes of their locals to what they were doing. The bible clearly teaches that I can pray in my closet, or I can take communion after my evening meal at home.
We meet to study together, commune together, and “share” our Christianity. At least, it’s why I go to church.

The OCs existed long before the catacombs...
