I would not place Mr. Huysman’s scholarship even in the same universe as the reknowned Dr. Jaroslav Pelikan of blessed memory, emeritus professor of history at Yale, who wrote the definitive biography of Patriarch +Josyp,
Confessor between East and West and knew him personally. In that biography he summarizes the work of Patriarch +Josyp in restoring the liturgical commemoration of St. Gregory. The copy of the actual
votum Dr. Pelikan accessed was then in Rome at the Patriarchal Library at St. Sophia (the UGCC Patriarchal Archives have since been moved to Kyiv).
It usually best to ground oneself on the universal liturgical maxim
lex orandi, lex credendi. Rome isn’t in the business of allowing liturgical commemoration or veneration of heretics damaging to the faith. So the *Anthologion * published in Rome in 1974 with the great efforts of Patriarch +Josyp, was approved with the approbation of the Holy See, and is therefore the definitive evidence.
In spite of lots of polemic on this forum to the contrary, Rome has never attempted to limit, rescind, abrogate, adjust, amend, or require anyone to cease and desist from the liturgical observance of St. Gregory on the second Sunday of the Great Fast which she herself approved in the
Anthologion published in Rome by the Sacred Oriental Congregation in 1974.
Of course the approbation by the Holy See of the
Anthologion in 1974 is now precedent not only for the UGCC but for any other particular Church of the Constantinopolitan tradition, and thus any other particular Church could do as the Melkites have done.
I’ll leave off this beaten horse with the edifying words of our UGCC Bishop +Basil of Stamford (now Emeritus) in his
Paschal Pilgrimage:
St. Gregory taught that all Christians are called to union with God, which is the subject of the Christian life… with the recent profound studies of St. Gregory, and the deeper appreciation of the Christian East, the Holy See restored St. Gregory’s memorial on the Second Sunday of the Great Lent in the Anthologion…our own Patriarch Joseph made a strong and positive contribution to this restoration of St. Gregory Palamas to Catholic liturgical practice…I am pleased to see that the new English translation of the *Lenten Triodion * contains the full service to St. Gregory Palamas, **and I am confident that this will increase our understanding of our spiritual and theological tradition. **
