What Biblical basis is there for Sunday Observance, besides a group of people sending food to the starving Saints in Jerusalem "on the first day of the week" ? 1 Corinthians 16: 1-2 / Romans 15: 25-28 OR ----------- the women visiting a tomb "on the first day of the week" OR ------------ A Saturday evening gathering together for a fellowship meal, where Paul spoke to the people, and kept on speaking until midnight, since he was going to leave the next day, Sunday ? (Acts 20:7) If every time a body of believers meet on a day and a preacher preaches a sermon, and that makes the day holy, there would be numerous Sabbath/holy days. Some churches hold Sunday evening meetings and meetings on Wednesday evenings. But neither of these is sacred beyond the act of worship itself.
