If one then examines Rahner's "transcendental Christology", it may be seen that it "presupposes an understanding of the relationship of "mutual" conditioning and mediation in human existence between what is transcendentally necessary and what is concretely and contingently historical". It is a sort of relationship between the two elements in such a way that "the transcendental element is always an intrinsic condition of the historical element in the historical self" while "in spite of its being freely posited, the historical element co-determines existence in an absolute sense". Transcendental Christology is "the experiences which man always and inescapably has". Human beings were created to freely transcend themselves and the objects in the world, towards the incomprehensible Mystery called God; the limitations of human situation make a human being hope that the full meaning of humanity and the unity of everything in the world will be fulfilled by God's self-giving. Furthermore, God's self-communication and human hope for it should be "mediated historically" because of "the unity of transcendentality and historicity in human existence": human hope looks in history for its salvation from God that "becomes final and irreversible, and is the end in an 'eschatological' sense". At this point Rahner proposes two possibilities of human salvation, i.e. either as "fulfillment in an absolute sense" which means the establishment of the Kingdom of God on earth, or as "a historical event within history". The event of human salvation by God's self-giving love should be the event of a human person, because God's salvific love can only be effective in history when a person "freely" accepts his love, surrenders everything to God in death, and in death is accepted by God. Rahner significantly affirms that the character of the saviour is exemplary and absolute: given the unity of the world and of history from the view point of both God and the world, such an "individual" destiny has "exemplary" significance for the world as a whole. Such a man with this destiny is what is meant by an "absolute saviour".
