"Most believers worship on “The Lord’s Day” or “Resurrection Day,” not the Seventh Day of the week as was in the beginning, which is the day non-completed Jews still worship."
What difference does it make how many people worship incorrectly? One plus God is always a majority.
I wasn't saying anything about any "incorrect day" but rather after Christ's resurrection, early believers chose to worship the Lord on the first day, the day He was resurrected, rather than the seventh day.
As The Lord himself, said, the "Sabbath was made for mankind, not mankind for the Sabbath."
