Communicatio In Sacris - Scholarly Study on Intercommunion

In this review of Communicatio in Sacris the reviewer finds a focused, scholarship-driven book for readers seeking a comprehensive historical account of intercommunion debates. The single biggest reason to buy is its exhaustive citation of primary and secondary sources documenting why the Roman Catholic Church has long prohibited intercommunicating with non-Catholics. This review notes the book's careful indexing, photographic documentation and clear thesis about the 1054 anathemas and their 1965 revocation, making it a work suited to study rather than casual reading for those interested in ecclesial practice and doctrinal history.

Key Features

• Comprehensive documentation: The book compiles and quotes from numerous scholarly sources to support its central argument about Catholic practice on intercommunion.
• Historical focus: It examines the 1054 anathemas and the 1965 revocation by Paul VI and Athenagoras I to contextualize the modern debate.
• Photographic evidence: Over 100 photos are included to illustrate documents and historical points referenced in the text.
• Index and references: A full index and documented quotes make the work easier to use for research and citation.
• Length and detail: At 290 pages the book provides sustained analysis useful for scholars, theologians and informed lay readers.

Who It's For

Communicatio in Sacris is best for Catholics, theologians, church historians and graduate students who require a densely referenced treatment of intercommunion and the legacies of the 1054 schism. The presence of an index and documentary photos makes it practical as a reference work for research papers, lectures or parish study groups focused on liturgical and canonical practice.

It is less suited to readers seeking a brief overview or devotional reading; lay readers wanting a light introduction to ecumenism may prefer shorter surveys of doctrine that are less densely footnoted and more narrative in tone.
