Why Christians Worship On The First Day Of The Week (Sunday)?

It had been said that all those worshiping on the First Day of the Week (Sunday) are not worshiping the true and only Almighty God. The Advocates of the "Sabbath Day" say all that gather on the first day of the week or Sunday to worship God will find themselves in hell because according to them, the Roman Catholic church initiated Sunday worship in honor of what they call their "sun god". According to them, the day of worship for all that serve the true God today must be Saturday or the last day of the week also known to them as the "Sabbath Day". But, is this "the truth"? Was the early church worshiping on the "Sabbath Day" in the Bible and the Catholic church later changed it to the first day of the week or Sunday? Do they have scriptures to prove their claim? Well, in this Book, we are going to study from the Bible to see whether the Sabbath Advocates are right or not. This book was not written because we want to prove the Sabbath Advocates wrong, rather, it was written to consider all their points and the scriptures they provide, from these points and scriptures, we will know whether they are right or not. This book helps its readers to understand everything they need to know about the Sabbath, the purpose of the Sabbath, the Law, the purpose of the law, and many more. All doubts will be cleared and all myths dealt with. We are going to remain with the scriptures and the scriptures only. God bless you.
