He was the brother of Hugo Rahner who was a German Jesuit and noted theologian and Church historian, who was Dean and President of the University of Innsbruck.
Rahner's work is characterized by the attempt to reinterpret traditional Roman Catholic theology in the light of modern philosophical thought.
He was ordained a priest in 1932 and continued his studies at the University of Freiburg. After receiving his doctorate in philosophy in 1936, he taught at the universities of Innsbruck and Munich. In 1967 he was appointed professor of dogmatic theology at the University of Münster. He was a peritus (official theologian) at the Second Vatican Council (1962-1965).

Rahner's thought is best described as a theological anthropology. Beginning with the nature of man as a being open to the infinite, Rahner's thought sees a person's quest for fulfillment satisfied only in union with the God of Christian revelation, the God who became man in Jesus Christ. A proper understanding of humans cannot be divorced from an understanding of God and the context of relationships uniting humans and God. The fundamental fact underlying the existence of the world is that it stands in relation to God. Rahner calls this situation the supernatural existential and sees in this fundamental fact the root of all further explanations of sin, grace, and salvation.
Rahner was buried at the Jesuit church of the Trinity in Innsbruck.
