@Aidan God never abolished or changed any of His commandments ,they are now written on our hearts and in our mind instead of stone
The Papacy upheld the change of the Sabbath ,changed by law by Constantine in 321 AD
Though its true many kept both days in the early church
But Paul was raised a Roman ,and more zealous in his beliefs than anyone until he met Christ
After that you see him teaching both Jew and Gentile on the 7th day
In Hebrews he even says the day remains for those who know Gods will
And shows that is why only 2 got into the promised land ,
They worshiped pagan gods (as does Rome ) and they defiled the Sabbath Day

To those who know Gods will ,the Sabbath should be observed from sundown Friday to Sundown Saturday

many pastors say it no longer matters ,I beg to differ with them
Even the Papacy says they will pay $1000.oo for 1 scripture that says to change the Sabbath ,
The fact no one can produce one show the Pope is not bound to scripture and can interpret Church doctrine and traditions as he see's fit ,,and since the world keeps Sunday over the 7th day proves he is right
