Coming together, as a body, in God’s presence, has been a part of our relationship with God from the first day He walked with Adam in the cool of the evening. When God laid out the Law through Moses, as He worked on turning this group of people into a true nation, He specifically told them to come to the place of meeting for certain feasts every year – no matter how far away they lived.
In Jesus’ day, they customarily went to Temple every week. We see repeatedly that it was Jesus’ custom throughout His ministry, and in the book of Acts we learn that the disciples continued to do the same. The disciples also met from house to house in the book of Acts.
I see an interesting progression here. At first, the requirement was to gather a few times a year, though obviously the more often a man came to Temple the better. In Jesus day, on the Sabbath was a standard. After the death, burial, and resurrection we see the true disciples meeting pretty much daily.
Now look at us. A very few who claim to be Christians meet twice a week. A few more meet once a week. The majority (here in the US anyway) who claim to be Christians might make it to church on Christmas and/or Easter.
It looks to me like we’re regressing rather than progressing.
