Although it occurs in only one patristic text and in no classical Roman sources or inscriptions,[5] the phrase has spawned abundant scholarly conjecture on its possible significance. Some scholars have gone so far as to imagine that all religions under the Empire had a legal status as either licita or illicita, despite the absence of any ancient texts referring to these categories.[6] The most extreme view has held that Tertullian's phrase means all foreign religions required a license from the Roman government.[7] However, it was Roman custom to permit or even to encourage the subject peoples of the Roman province and foreign communities in Rome to maintain their ancestral religion unless specific practices were regarded as disruptive or subversive:[8] "A religio was licita for a particular group on the basis of tribe or nationality and traditional practices, coupled with the proviso that its rites were not offensive to the Roman people or its gods."[9]
Tertullian uses the phrase in a passage arguing that Christians should be granted the same freedom to practice their religion as any other of the empire's inhabitants; the passage itself, not the phrase religio licita, is evidence of the general tolerance afforded under the Roman system of religion.[10]

^Philip Francis Esler, Community and Gospel in Luke–Acts: The Social and Political Motivations of Lucan Theology (Cambridge University Press, 1989, 1996), p. 211, begins his analysis of the religio licita theory "by immediately scotching the idea that Rome had some process for licensing foreign religions. There is no historical support for this whatsoever; ... there never was a juridical category of religio licita."
