In 1972, Communio was begun by Hans Urs von Balthasar, Henri de Lubac, and Joseph Ratzinger, among others. And Communio offers academic theological articles on the mysteries of faith, which take inspiration from the whole tradition of the Church, from the Fathers of the Church to the literary and theological authors of twentieth-century Ressourcement (return to the sources).
In each of the quarterly issues, one can typically find about ten articles of academic theology coverting the full range from soteriology, Christology, Mariology, ecclesiology, eschatology, Scriptural approaches, ecumenism, etc. These articles feature original work and translations of articles from Communio journals from other countries. In addition, the occaisional "Retrieving the Tradition" and "Spirit and History" sections feature reprints and new translations from the tradition of the Church: from Maximus the Confessor to Dorothy Day.
Do I read and understand each article? No. I am just an amateur theologian. I subscribe to Communio because each issue contains one or more article that proposes new ways to broaden and deepen my understanding of the faith.
