As historians such as John Owens claim, many early Christians rejected the names of the days of the week because of the connotations associated with Pagans. Even in 'Augustine of the Psalms 93', Wednesday is referred to as the Day of Mercury (however, as Owen's retells it, the author of the Psalm obviously shows distaste to the name).

Albert Barnes in Barnes Notes on the NT, argues that Christians would have called Sunday 'Sabbath' to keep with the tradition of their Jewish roots. World History - A Christian Interpretation by Albert Hyma continues in this vein saying they moved from calling it the Sabbath and referring to Sunday as 'the Lord's Day'.

In 'The World Ended on a Friday', Rev. David Bauscher delineates that the early Christians referred to the days of the week by the number of its order i.e. Monday = "erku-Shabti" (second of seven) etc. However, Friday is labelled as "erbat" which means 'evening' in Aramaic.
