Nexus Infinitas is the most important example of apocalyptic literature written on the Earth since Saint John the Divine penned Revelation. Skeptical? Read it and discover the truth—or be left behind.

In this third volume of Collected Essays, Peter Damian Fehlner traces the Franciscan Marian-ecclesiological vision and mission back to its sources in Francis and Clare of Assisi. Fehlner shows how the quintessentially Franciscan theological themes and their elaboration down the centuries find their roots in the Poverello, the “Man totally Catholic and Apostolic,” as well as in Clare, the “imprint of the Mother of God.” In thoroughly Trinitarian fashion, Fehlner unveils Francis’s understanding of Mary—type and exemplar, mother and member of the church—as the firstborn daughter of the Father, Mother of the Son, and Spouse of the Holy Spirit. Mary is, therefore, primordially the Virgin-made-Church. Flowering out into the Franciscan theological tradition, this volume features two studies where Fehlner unpacks this Franciscan, Marian-ecclesiological tradition in systematic and mystical theology. Fehlner takes St. Francis Anthony Fasani, his Conventual predecessor, as his guide in the spiritual exegesis of Scripture and Catholic devotion, unveiling the ecclesiological and Marian implications of the Song of Songs. In systematics, Fehlner analyzes the love song of the Son for his church in his definitive study of Bonaventure’s understanding of charity and the divine missions in the church.

This fourth book in the Nexus series offers papers that further broaden the horizons of studies in architecture and mathematics.
