As well, was and....did Our Lord.
Then to celebrate and observe their belief in Christ they got together on Sunday and blessed the bread and wine as Christ had instructed them to do in remembrance of him. Thus, the celebration of Sundays began with the Apostles.
This is totally unscriptural and never happened. You will be unable to provide one verse that would even hint of this. This is a totally false doctrine established by your Magesterium to justify the observance of "Sol Invictus".... as had your Roman predecessors.
I'll pray for you, because thoe people in the Magisterium knew a lot more about how things went in the early church that I (or you) might know at this time.
Have a blessed Saturday, then!
