Acts 17:7

Contrary to the decrees of Caesar. The charge at Philippi was that of introducing new customs; but as Thessalonica was not a colony, that charge could have no force there. The accusation substituted is that of treason against the emperor; that of which Jesus was accused before Pilate. "The law of treason, by which the ancient legislators of the republic had sought to protect popular liberty from the encroachments of tyranny,... was gradually concentrated upon the emperor alone, the sole impersonation of the sovereign people. The definition of the crime itself was loose and elastic, such as equally became the jealousy of a licentious republic or of a despotic usurper" (Merivale, " History of the Romans under the Empire ").
