What is the Lord's day?
- 1. The Lord's day is just another name for the Sabbath.
- 2. The Lord's day is a Second Sabbath, like the weekend.
- 3. The Lord's day is a Replacement Sabbath, or new Sabbath on a new day.
- 4. The Lord's day is like a prayer meeting, an additional service to the Sabbath, that usurped it.
- 5. The Lord's day is a Pagan day, that came into Christianity
- 6. The Lord's day is the day of his victory, the day I was coming.
If I remember correctly, most Sunday observing Christians in the second century CE would likely choose # 3. Sunday became the new "Sabbath" and by medieval times Sunday was often rendered as "Sabbath".
