Since the Roman Catholic Church claims her own power and authority to change the worship day of God from Saturday-the seventh-day of the week to Sunday-the first day, and not the power and authority of God as found in His Scriptures, then Sunday is purely and only a worship day created by the Roman Catholic Church and not God!
Kutokana na kwamba Kanisa Katoliki la Kirumi hudai uwezo wake lenyewe na mamlaka kubadilisha siku ya ibada ya Mungu kutoka Jumamosi siku ya saba ya juma kwenda Jumapili siku ya kwanza, na siyo uwezo na mamlaka ya Mungu kama inavyopatikana katika Maandiko yake, basi Jumapili ni dhahiri kabisa na siku tu ya ibada iliyoumbwa na Kanisa Katoliki la Kirumi na siyo Mungu!
