How Did The Sabbath Change From Saturday to Sunday In Christendom?

Have you wondered how the early Christian church decided to change the day of worship from Saturday to Sunday? This has been a contentious issue between the few Christians who still worship on Saturday and the majority who worship on Sunday. Most Sunday keepers say that it was the apostles who decided to change the day of worship from Saturday to Sunday in remembrance of the resurrection which took place on a Sunday. On the other side, those who worship on Saturday insist that it was not made by the apostles but much later by an apostate church and that there is no scriptural basis for doing so. They say this is exactly what Christ warned about when he said, 'in vain they do worship me, teaching for doctrine the commandments of men'. If the change is man made then those who worship on Sunday better heed the warning of Christ on worshiping in vain by teaching for doctrines the commandments of men. 

 To find out how the change occurred Dr Samuele Bacchiocchi spent five years at the Pontifical Gregorian University in Rome examining most ancient documents available. His investigation established that the change from Saturday to Sunday began approximately one century after the death of Christ as a result of an interplay of political, social, pagan and Christian factors. The results of this research are presented in the book From Sabbath to Sunday. This book which originally Dr Bacchiocchi's dissertation has the distinction of being the first book written by a non-Catholic ever to be published by a Pontifical press Catholic approval. Hundreds of scholars have praised Dr Bacchiocchi's book and consider it definitive study on the history of the change of the Lord's day.
