There are some obvious differences between my church and the early church. The architecture and layout of my church is much more modern and basic, no art on the walls, the baptismal tank is in the sanctuary hidden until needed, and there is no natural light in the sanctuary at all.
Baptisms are done multiple random times a year, with participants clothed, and baptized solely by the pastor. This is as opposed to naked baptisms around Easter done by the deacon or deaconess of your gender.
Another difference is the order of service, and worship. No one is asked to leave if they have not yet been baptized, no one kisses each other, and the Eucharist/communion is only performed once a month, on the first Sunday.
