The earliest recorded effort to switch the Sabbath that I have found is in a false prophesy in the Epistle of Barnabas early in the 2nd century.

Barnabas 15:8
Finally He saith to them; Your new moons and your Sabbaths I cannot away with. Ye see what is His meaning ; it is not your present Sabbaths that are acceptable [unto Me], but the Sabbath which I have made, in the which, when I have set all things at rest, I will make the beginning of the eighth day which is the beginning of another world.
Barnabas 15:9
Wherefore also we keep the eighth day for rejoicing, in the which also Jesus rose from the dead, and having been manifested ascended into the heavens.

Of course, we know that this did not take root, as there had to be a civil law to enforce this heresy over 200 years after it was penned.

"false prophesy in the Epistle of Barnabas"

Is this book about as valid as the baby gospels and the other books that have been determined as to be not inspired by God?
