Sunday worship or Saturday in Biblical Issues Posted May 8, 2009 · Report reply The first century Jesus followers were Christian Jews - they continued to observe the sabbath as the Jews have always done. However the task of preaching and teaching seemed to be breaking the sabbath (the Pharisees even chastised Jesus for healing the sick on a sabbath.) The new Jesus Followers made the first day of the week the day to celebrate the resurrection of Christ - and to separate itself from the Jewish sabbath day customs. Remember the jews have a lot of strict religious laws regarding how the sabbath is to be kept (you can only travel so far, etc.). I take the whole weekend off myself - I rest on the seventh day of the week (Saturday) and I worship on the first day of the week (Sunday) - but I live my life for Christ EVERY day of the week.
