The early Churches architecture was something that was quite wonderful. Some simulairites is that my church is mostly lit with natural light in the sanctuary. My Church is fairly basic with no art upon the walls. We have quite a few rooms in our Church that all serve different peruses.
Our worship part looks different that the early Church. Their focus seemed to be based around the Eucharist whereas ours is more based around the preaching. We also do not ask people to leave if they are not baptized and we do not greet each other with a kiss.
We normally only celebrate the Eucharist at the beginning of each month not every time we meet together.
When someone in the Church wants to be baptized, we usually go out to a lake and baptize someone there. We do not have a set date when we baptize everyone, we just do it whenever someone wants to be baptized.
