Religious law centered on the ritualised system of honours and sacrifice that brought divine blessings, according to the principle do ut des ("I give, that you might give"). Proper, respectful religio brought social harmony and prosperity. Religious neglect was a form of atheism: impure sacrifice and incorrect ritual were vitia (impious errors). Excessive devotion, fearful grovelling to deities and the improper use or seeking of divine knowledge were superstitio. Any of these moral deviations could cause divine anger (ira deorum) and therefore harm the State. The official deities of the state were identified with its lawful offices and institutions, and Romans of every class were expected to honour the beneficence and protection of mortal and divine superiors. Participation in public rites showed a personal commitment to their community and its values.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did participation in public religious rites show about the individual?
commitment
