I recognize the truth of what yhou say, that they were 24/7/365 Christians who witnessed to Christ with every fiber of their being.
I did not, however, say that they were once-a-week churchgoers. I said that Sunday beame a special day so prayer for them when they gathered. This --- as well as fervent daily devotion and action for Christ -- is attested to in Acts and in the earliest hisrtorical records we have.
Both --- daily lively faith life, and weekly special gtherin on Sunday --- are from the earliest times.
I know that is what you have been taught. I know that is what you believe. But that is un-Biblical. Jesus was accused of profaning the Sabbath but in reality He never did. He defined it. The transferrence of Sabbath to Sunday as Gods day of rest is not in recorded history. It happened in the early centuries as Sun god worshipers were inducted (along with other pagan practices) into churches. The Pharisees were a devout sect as well but they were just as wrong as Christ denounced them.
