How did the Sabbath change from the seventh day of the week to the first day of the week? And who changed it? Who authorized such a drastic alteration in the law of God that declares that He "changes not" (Malachi 3:6)?
In order to answer these questions, many turn to the early "fathers" of the Christian Church and look for some evidence which can justify an alteration in the law of the Ruler of the Universe! But how vain is this endeavor.
In The Complete Testimony of the Fathers, originally published in 1873, J.N. Andrews presents unanswerable evidence that clearly shows how this change took place and who authorized it.
