Anonymous Christian is the controversial Christian doctrine concerning the fate of the unlearned which was introduced by the Jesuit theologian Karl Rahner (1904–1984) that declares that all individuals, who sincerely seek truth and goodness, and strive to follow the moral truths they know, can respond positively to God's grace, albeit unknowingly or indirectly, even if they do so through other religious traditions and/or are not explicitly aware of Jesus Christ. In other words, God's grace, including the benefits of Christ's sacrifice, are not confined to the boundaries of any particular religious tradition or by our awareness or acceptance of Christian doctrine. Instead, anyone who lives a life of love and goodness, guided by the moral teachings found in Christianity, even if they don't consciously identify with it, is implicitly united with Christ and can be saved through him, implying that non-Christians can still be recipients of God's grace and attain salvation.
Non-Christians could have "in [their] basic orientation and fundamental decision," Rahner wrote, "accepted the salvific grace of God, through Christ, although [they] may never have heard of the Christian revelation."[1]
The notion of inclusivism, for which Rahner's Anonymous Christian is the principal Christian model, is "perhaps the most popular of interreligious postures"[2] and was one of the most influential theological ideals to affect the Second Vatican Council.[3]
