A third school asserted that Christians were prosecuted for specific criminal offenses such as child-murder, incest, magic, illegal assembly, and treason – a charge based on their refusal to worship the divinity of the Roman emperor. Sherwin-White says "this third opinion has usually been combined with the coercitio theory, but some scholars have attributed all Christian persecution to a single criminal charge, notably treason, or illegal assembly, or the introduction of an alien cult". In spite of ubiquitous rumors, this theory has been the least verified of the three by later scholarship.
