The Catholic Encyclopedia says Origen and Clement of Alexandria were the first to teach universal salvation: "The doctrine, then, was first taught by Origen, and by Clement of Alexandria, and was an influence in their Christianity due to Platonism, as Petavius has plainly shown . . ." Ilaria L. E. Ramelli has questioned such a narrative in her work titled "Origen, Bardaisan, and the Origin of Universal Salvation," and, as far as I can tell, she has plainly shown the opinion above to be outdated in terms of research. Here I'll present her abstract: "Is Origen of Alexandria the inventor of the eschatological doctrine of apokatastasis— of the eventual return of all creatures to the Good, that is, God, and thus universal salvation? Certainly, he is one of its chief supporters in all of history, and he is, as far as we know, the first to have maintained it in a complete and coherent way, so that all of his philosophy of history, protology, and anthropology is oriented toward this telos.1 There are, however, significant antecedents to his mature and articulate theorization, at least some of which he surely knew very well, and there is even a possible parallel. For this conception did not appear ex nihilo, but in a cultural context rich in suggestions and premises, and in a philosophical framework of lively discussions concerning fate, free will, theodicy, and the eternal destiny of rational creatures." These "significant antecedents" include Bardaisan (who was possibly Clement's Syrian teacher that "received the tradition from the apostles through oral transmission"), the Apoc of Peter (dated by some scholars around the time of the Bar Kokhba revolt), and more. Also, the Catholic Encyclopedia states universal salvation "was an influence in their Christianity due to Platonism." Well, universalists in early Christianity first and foremost rooted their teaching in scripture and the Christian tradition. According to Origen and the tradition he said he received, the doctrine was announced by the prophets (Jer. 15.19; Acts 3.21).
