Book excerpt: This insightful study offers the first comprehensive overview of the theology and praxis of Roman Catholic theologian Heribert M hlen. This theologically accurate and historically sensitive book shows that M hlen has gone beyond his popular early academic exercise by documenting and proposing a liturgical praxis that aims at providing a concrete framework for the acceptance and renewal of the human covenantal relationship with God. In every respect, M hlen's theology and praxis marks the beginning of a new profile of the Church. A letter and epilogue by Heribert M hlen are included.
