What is "religious deviation"? These are acts that are supposed to violate a norm generally valid for a part of a historical society. But can we reconstruct a uniform discourse on the limits of acceptable religious behavior? In fact, we have at our disposal normative texts of very different characters. The inclusion of religion in the system of law is a very important process, developing up to the norms accumulated in Book 16 of the Theodosian Code in the 4th and5th centuries. In ancient descriptions of religious practices, deviance is only occasionally mentioned. Historical descriptions are typically anecdotal in nature, focusing on a few individual cases. Alongside this, there are a few sociocritical satirical or philosophical texts, for example on "superstition".
In line with sociological and criminological research on deviance, we need to look at normalization and the construction of deviation. A first step is taken with the normative texts of the Roman republic, ancient legal fragments such as the two great sums that are Varron's Divine Antiquities and Cicero's Laws. In these texts, we examined explicit statements about, and implicit allusions to, religious deviance, from a semantic point of view and from the perspective of behavior described as deviant. Surprisingly, the normative texts of the late Roman republic do not speak of the margins of Roman religion. Other religions existed - outside, according to Varron. Cicero aims for universalization - his texts accompany the formation of a world empire.
The analysis then focused on the works of Seneca and Plutarch (1st century AD), who saw "superstition" as a potentially dangerous activity for religion. But the voices of these two intellectuals are not the only ones to be heard. Others developed a more positive vision. Heron of Alexandria describes a series of instruments and mechanisms designed to create an emotional confrontation with the god in the temple. Here, religious experience is an essential element of living religion.
