The Patriarchal Greek New Testament (PATr) was published by the Patriarchal Press of the Ecumenical Patriarchate of Constantinople on February 22, 1904. It was published as The New Testament, Approved by the Great Church of Christ, with a goal to be the most authoritative text of the Greek New Testament available for Orthodox churches.
As more critical or eclectic editions of the NT became the norm by the nineteenth century (replacing the Byzantine Text), the Patriarchate assembled a committee of scholars for studying multiple manuscripts of the NT from both Constantinople and Mount Athos. Their goal was to provide "the best reconstruction of the most ancient text of ecclesiastical tradition and, more specifically, of the Church of Constantinople" (from the preface to the 1904 edition). The manuscripts they selected were from the ninth to the sixteenth centuries, and were largely from lectionaries (that is, from texts that were actually used in the worship of the Church). After the Patriarchal Greek New Testament's initial publication in 1904, Professor Vasileios Antoniades of the Theological School of Chalki made some minor corrections to the text in 1912.
The morphological tagging in this edition of the Patriarchal Greek New Testament, prepared by Logos Bible Software, integrates with other resources tagged with the Logos morphology, making it possible to perform searches across numerous morphologically tagged texts such as the Septuagint, Pseudepigrapha, Apostolic Fathers, Philo, and Josephus. This allows for ease of comparison in examining the usage of various grammatical and morphological constructions across a variety of authors and Greek texts.
