God wishes that everyone be saved and achieved a knowledge of the truth, but Jesus affirmed that in order to be saved it s necessary to believe and be baptized. Faced with these two biblical axioms, theology has questioned itself, since the end of the 19th century, about the possible ways of access to the same salvation for non-Christians who ignore, through no fault of their own, the gospel. The Second Vatican Council s gathered the first contributions of the theology of religions, verified the existence of elements of truth in other religions and recognized the seeds of the Verb that the Fathers of the Church affirmed to exist in every human. It presented the possibility of its members, by a mysterious grace of God, being inserted in the single and universal economy of salvation of the Holy Trinity. Two topics directing the investigation of a soteriological way beyond Christianity, which considers Jesus as mediator and universal redeemer. The first is the declaration Dominus Iesus, written to recall the principles of the Christian faith against the proposals of the theology of religious pluralism, which suggested a salvific economy parallel or complementary to that brought by Christ in communion with the Holy Spirit. The second is the works of Saint Justin of Rome, who fetched to identify the soteriological elements that allow Jews and pagans to have access to Jesus and achieve salvation. For pagans, he observed components of truth and Logos, with special emphasis on Logos spermatikós, recognized as particles of God in each human. For the Jews, who presented the Law, the saturday and circumcision as salvific elements, Justin points to baptism as the true circumcision, Jesus as the true saturday and the Church as the New Law. From these contributions, the research presents the theological places where the salvation of non-Christians can be identified.
