"Those who are enlightened by God know Him truly, as did some of the Orthodox Popes of Rome before that Church's fall, but this knowledge is solely the product of union with Christ, both in the case of the pauper and the Pope, as St. Gregory so eloquently argues in his essay
Περὶ Θείας καὶ Θεοποιοῦ Μεθέξεως [On Divine and Deifying Participation] (Chrestou, op. cit., Vol. 3, pp. 212-261). The very structure of Palamite theology disallows any attribution of universal jurisdiction or authority, except in the traditional sense of 'honor' and 'eminence,' to anyone in the Church. St. Gregory resolutely and unequivocally identifies true teaching and all authority with spiritual enlightenment, which, in turn, is the product of a true and genuine encounter with God shared by all enlightened individuals in common and equally. Hesychasm is a direct condemnation of Papism." (pp. 26f., emphasis in original)
Original text (in Italian)
Speaking of the hesychast controversy, Pope John Paul II said the term "hesychasm" refers to a practice of prayer marked by deep tranquillity of the spirit intent on contemplating God unceasingly by invoking the name of Jesus. While from a Catholic viewpoint there have been tensions concerning some developments of the practice, the Pope said, there is no denying the goodness of the intention that inspired its defence, which was to stress that man is offered the concrete possibility of uniting himself in his inner heart with God in that profound union of grace known as Theosis, divinization.
