The traditional view of Gregory is that he was an orthodox
Trinitarian theologian, who was influenced by the
Neoplatonism of
Plotinus and believed in
universal salvation following
Origen. However, as a highly original and sophisticated thinker, Gregory is difficult to classify, and many aspects of his theology are contentious among both conservative
Eastern Orthodox theologians and Western academic scholarship. This is often due to the lack of systematic structure and the presence of terminological inconsistencies in Gregory's work.
Conception of the Trinity Gregory, following Basil, defined the Trinity as "one essence
οὐσία] in three persons
ὑποστάσεις]", the formula adopted by the Council of Constantinople in 381. Like the other Cappadocian Fathers, he was a
homoousian, and
Against Eunomius affirms the truth of the
consubstantiality of the trinity over Eunomius' Aristotelian belief that the Father's substance is unengendered, whereas the Son's is engendered. According to Gregory, the differences between the three persons of the Trinity reside in their differing hypostatic origin, and the triune nature of God is revealed through divine action (despite the unity of God in His action). The Son is therefore defined as begotten of the Father, the Holy Spirit as proceeding from the Father, and the Father by his role as progenitor. However, this doctrine would seem to
subordinate the Son to the Father, and the Holy Spirit to the Son.
Robert Jenson suggests that Gregory implies that each member of the
Godhead has an individual priority: the Son has
epistemological priority, the Father has
ontic priority and the Spirit has
metaphysical priority. Other commentators disagree:
Morwenna Ludlow, for instance, argues that epistemic priority resides primarily in the Spirit in Gregory's theology. Modern proponents of
social trinitarianism often claim to have been influenced by the Cappadocians' dynamic picture of the Trinity. However, it would be fundamentally incorrect to identify Gregory as a social Trinitarian, as his theology emphasises the unity of God's will, and he clearly believes that the
identities of the Trinity are the three persons, not the relations between them. An important consequence of Gregory's belief in the infinity of God is his belief that God, as limitless, is essentially incomprehensible to the limited minds of created beings. In
Life of Moses, Gregory writes: "...every concept that comes from some comprehensible image, by an approximate understanding and by guessing at the Divine nature, constitutes an idol of God and does not proclaim God." Gregory's theology was thus
apophatic: he proposed that God should be defined in terms of what we know He is not rather than what we might speculate Him to be. Accordingly, the Nyssen taught that due to God's infinitude, a created being can never reach an understanding of God, and thus for man in both life and the afterlife there is a
constant progression [ἐπέκτασις] towards the unreachable knowledge of God, as the individual continually transcends all which has been reached before. In the
Life of Moses, Gregory speaks of three stages of this spiritual growth: initial darkness of
ignorance, then spiritual
illumination, and finally a darkness of the mind in mystic
contemplation of the God who cannot be comprehended.
Universalism , 10th century Gregory was one of the earlier proponents of
Christian universalism. Gregory argues that when Paul says that God will be "all in all" (), this means that though some may need to undergo a long period of purification, eventually "no being will remain outside the number of the saved" and that "no being created by God will fall outside the Kingdom of God". Due to the unity of human nature in Christ "all, thanks to the union with one another, will be joined in communion with the Good, in Jesus Christ Our Lord". Christ's incarnation, death and resurrection results in "total salvation for human nature". Gregory also described God's work this way: "His [God's] end is one, and one only; it is this: when the complete whole of our race shall have been perfected from the first man to the last—some having at once in this life been cleansed from evil, others having afterwards in the necessary periods been healed by the Fire, others having in their life here been unconscious equally of good and of evil—to offer to every one of us participation in the blessings which are in Him, which, the Scripture tells us, 'eye hath not seen, nor ear heard,' nor thought ever reached." That this is what Gregory believed and taught is affirmed by most scholars. A minority of scholars have argued that Gregory affirmed only the universal resurrection. In the
Life of Moses, Gregory writes that just as the darkness left the Egyptians after three days, perhaps redemption
ἀποκατάστασις] will be extended to those suffering in
hell γέεννα]. This salvation may extend not only to humans; following
Origen, there are passages where he seems to suggest (albeit through the voice of Macrina) that even the
demons will have a place in Christ's "world of goodness". Gregory's interpretations of 1 Cor. 15:28 ("And when all things shall be subdued unto him ...") ("That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth") support this understanding of his theology. While he believes that there will be no more evil in the hereafter, it is arguable that this does not preclude a belief that God might justly damn sinners for eternity. Thus, the main difference between Gregory's conception of ἀποκατάστασις and that of Origen would be that Gregory believes that mankind will be collectively returned to sinlessness, whereas Origen believes that personal salvation will be universal. After all, at the end of chapter XXXV of the
Great Catechism Gregory writes that those who have not been purified by water through baptism "must needs be purified by fire" so that "after long succeeding ages, their nature may be restored pure again to God". Attempting to reconcile these disparate positions,
Eastern Orthodox theologian Dr. Mario Baghos notes that "when taken at face value the saint seems to be contradicting himself in these passages; on the one hand he asserted the salvation of all and the complete eradication of evil, and, on the other, that the fire needed to purge evil is 'sleepless', i.e. everlasting. The only solution to this inconsistency is to view any allusion to universal salvation in St Gregory as an expression of God's intention for humanity, which is in fact attested to when his holy sister states that God has "one goal ... some straightway even in this life purified from evil, others healed hereafter through fire for the appropriate length of time." That we can choose either to accept or ignore this purification is confirmed by the saint's many exhortations that we freely undertake the virtuous path." Dr.
Ilaria Ramelli has made the observation that for Gregory free will was compatible with universal salvation since every person would eventually accept the good having gone through purification. However, Ramelli renders the original Greek "εἰς ἄπειρον παρατείνεται ἡ διὰ τῆς καθάρσεως κόλασις" as "the punishment provided for the purpose of purification will tend to an indefinite duration."
Anthropology Gregory's
anthropology is founded on the ontological distinction between the
created and uncreated. Man is a material creation, and thus limited, but infinite in that his
immortal soul has an indefinite capacity to grow closer to the divine. Gregory believed that the soul is created simultaneous to the creation of the body (in opposition to Origen, who believed in
preexistence), and that
embryos were thus persons. To Gregory, the human being is exceptional, being created in the
image of God. Humanity is
theomorphic both in having self-awareness and
free will, the latter which gives each individual existential power, because to Gregory, in disregarding God one negates one's own existence. In the
Song of Songs, Gregory metaphorically describes human lives as paintings created by apprentices to a master: the apprentices (the human wills) imitate their master's work (the life of Christ) with beautiful colours (
virtues), and thus man strives to be a reflection of Christ. Gregory, in stark contrast to most thinkers of his age, saw great beauty in
the Fall: from Adam's sin from two perfect humans would eventually arise myriad. Gregory used Plato's definition of virtue as ‘something that admits of no master [ἀδέσποτον]’ in the service of his own theological arguments against slavery: (1) each human is an image of God and therefore free, (2) the equality of all humans reflects the equality of the divine Persons and (3) just as the divine nature cannot be divided into slavery (δουλεία) and mastery (δυναστεία, κυριότης), neither can human nature; the whole creation is a slave but of God alone. Although the stoic
Seneca had criticized cruel slave masters and
advised slave masters to treat slaves with kindness (or at least those of good character), the
stoics never questioned the institution of slavery, which was considered an ordinary part of daily life in the ancient world; and other ancient philosophers such as
Plato and
Aristotle also supported slavery. Gregory of Nyssa's critique was the first and only sustained critique of the institution of slavery itself made in the ancient world.
Neoplatonism There are many similarities between Gregory's
theology and
Neoplatonism, especially that of
Plotinus. Specifically, they share the idea that the reality of God is completely inaccessible to human beings and that man can come to see God only through a spiritual journey in which knowledge (
gnosis) is rejected in favour of meditation. Gregory does not refer to any Neoplatonist philosophers in his work, and there is only one disputed passage which may directly quote Plotinus. Considering this, it seems possible that Gregory was familiar with Plotinus and perhaps other figures in Neoplatonism. However, some significant differences exist between Neoplatonism and Gregory's thought, such as Gregory's assertion that beauty and goodness are equivalent, which contrasts with Plotinus' view that they are distinct qualities. However Plotinus does say, "And Beauty, this Beauty which is also the Good", implying the
Monad which is the Good is also Beauty in Enneads 6:1, Beauty:6.
Eastern Orthodox theologians are generally critical of the theory that Gregory was influenced by Neoplatonism. For example,
Hierotheos Vlachos argues in
Life After Death that Gregory opposed all philosophical (as opposed to theological) endeavour as tainted with worldliness. This view is supported by
Against Eunomius, where Gregory denounces Eunomius for placing the results of his systematic
Aristoteleanism above the traditional teachings of the Church. == Feast day ==
