Why were the ancient Sunday laws demanded?

Answer

"That the day might be devoted with less interruption to the purposes of devotion!' "That the devotion of
the faithful might be free from all disturbance."-Neander's "Church History," Vol. II, pages 297, 301.
NOTE-In short, it was to secure the enforced observance of the day, and through this means
church attendance, and control over the people in religious things.
