"Protestants now urge that the resurrection of Christ on Sunday made it the Christian Sabbath. But Scripture evidence is lacking. No such honor was given to the day by Christ or His apostles.

"And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months. And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven. And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations."
