Based on the search results, Christians did not initially attend church every Sunday. Here are the key points:
1. The early Christians initially continued to observe the Jewish Sabbath (Saturday) as their day of rest and worship[4].
2. The shift to Sunday worship happened gradually over a period of about 200 years after Christ[4]. This change was not based on biblical command, but rather on tradition and attempts to differentiate from Jewish practices[4].
3. Sunday became associated with Christian worship because it was the day Jesus rose from the grave[1]. The New Testament mentions early Christians gathering on the first day of the week (Sunday) in Acts 20:7 and 1 Corinthians 16:2[2].
4. The practice of regular Sunday worship developed over time, becoming more established in the 2nd-4th centuries AD. It was not a direct biblical mandate[4].
5. Some argue that while Sunday worship became traditional, there is no strict biblical obligation to attend church every single Sunday[1][2]. The emphasis is more on regular gathering with other believers for worship, teaching, and fellowship, rather than a specific day[2].
In summary, weekly Sunday church attendance developed as a Christian tradition over time, but it is not explicitly commanded in the Bible. The New Testament emphasizes regular gathering of believers without specifying a particular day.
