Introduction
The potential existence of a true religion of universal origin (from Adam or from nature) is accepted by Jewish, Christian and Islamic thinkers. According to them, it would be possible to recognise its influence on pagans[1] ; this idea opens the door to speculation in relation to traces of truth even in the midst of what the Faith condemns as arising from error or idolatry. Christian theologians in Christian antiquity hover between two explanatory scenarios: either they postulate (as did Tertullian[2] and Augustine of Hippo[3] ), the existence of pagans enlightened from a source of nature, aware of the existence of a single and unique creator god; or they affirm (amongst others, Justin of Neapolis[4] , Lactantius[5] ), that in the wildest imaginings of paganism, and in the very deceits of the Devil, it is possible to find truths, veiled, distorted, but there all the same.
