Thesis advisor: Khaled Anatolios / Within the context of his controversy with Eunomius of Cyzicus, Gregory of Nyssa articulated a distinctly pro-Nicene conception of the perfection of God. Gregory identified divine perfection with the philanthropic goodness that is manifested in the economic activity of God and that is witnessed most vividly in the saving incarnation and death of Jesus Christ. Yet, while this particular understanding of divine perfection served Gregory’s defense of Nicene trinitarian theology, its influence was not limited to that element of his theology alone. To the contrary, Gregory’s pro-Nicene conception of the nature of divine perfection finds a perfect corollary in his discussion of the nature of human perfection. Thus, in his anthropological writings, Gregory interprets humanity as a living and active mirror of the characteristic goodness and love of divine power. Similarly, in his ascetical literature, he suggests that the goal of the Christian life is the attainment of godlikeness through participation in divine perfection, and that the form which this participation takes is an imitation of the virtues of Jesus Christ. And in his writings on the spiritual ascent of the soul, Gregory identifies the summit of the virtuous life as active participation in the philanthropic goodness of God. Christian virtue, therefore, is nothing other than imitation of and participation in the perfection of the one whom Gregory calls “the God of the gospel,” the God of Nicaea, the God made known in the person of Jesus Christ. / Thesis (PhD) — Boston College, 2020. / Submitted to: Boston College.

The aim of this thesis is to explore Gregory of Nyssa’s tabernacle imagery, as presented in Life of Moses 2.170-201. This part of Life of Moses has suffered from relative neglect compared to the scholarly attention conferred on Gregory’s apophatic darkness imagery. For the purposes of this study, Life of Moses 2.162-201 has been divided into nine consecutive sections, given the following headings: Darkness; The tabernacle ‘not made with hands’; Christological interpretation; Divine names; Heavenly powers; The earthly tabernacle; Heavenly and earthly worship; The holy of holies; The priestly vestments. Each section is analysed in the same way. Firstly, Gregory’s text is examined, and his biblical sources identified. Secondly, there is a presentation of relevant passages in the work of his Alexandrian predecessors – Philo, Clement and Origen. Thirdly, there is a discussion of the ways in which Gregory’s fourth century theological context has influenced his interpretation, often causing him to differ from his predecessors. It is under this heading of ‘theological context’ that contemporary scholarly discussions about Gregory are most in evidence. Fourthly, a heuristic comparison with a range of heavenly ascent texts from the Hellenistic and Late Antique worlds is undertaken. It is this methodology of heuristic comparison which is the experimental aspect of the thesis. The aim is not to prove influence, but to use heavenly ascent texts as a foil, in order to shed new light on Gregory’s imagery. Does Gregory’s interpretation of the tabernacle come into focus when viewed through the lens of heavenly ascent? In order to answer this question, the scholarship on heavenly ascent texts is mined for new ways of looking at Life of Moses. The conclusions begin by reviewing the methodology. It is argued that although many of the themes explored stem from the biblical text, and occur in Gregory’s Alexandrian predecessors, the richness of possibilities they provide, and therefore the choices made by Gregory, only become apparent when his work is compared and contrasted with a wide range of other heavenly ascent texts. Even in the case of a fourth century Christian work heavily influenced by Platonism, attending to the Jewish matrix of Christian mysticism pays dividends. The conclusions continue by listing the key ideas discovered in Life of Moses 2.170-201. They end by discussing the relationships between mysticism, theology and politics in Gregory’s tabernacle imagery. It is argued that Gregory holds all three together. This is typical of heavenly ascent texts, which combine descriptions of religious experience with claims to authoritative knowledge. For Gregory, the high point of Moses’ ascent into the darkness of Mount Sinai is the mystery of Christian doctrine. The heavenly tabernacle is a type of the heavenly Christ. This mystery is beyond intellectual comprehension, it can only be grasped by faith; and only the select few, destined for positions of responsibility, should even attempt to do so. But its benefits are available to all through the community’s worship in the earthly tabernacle. Anyone can aspire to wear an airy, angelic robe by living a life of virtue, in which faith and practice go hand in hand.

Comachara cadburyi Franclemont has benn classified as a sarrothripine (Noctuidae), lithosiine (Arctiidae), and afridine (Nolidae). Larval morphology and behavior indicate a close phylogenetic relationship with Polygrammate hebraeicum Hübner, an acronictine noctuid. The egg and larva of Comachara are described and illustrated with line drawings and scanning electron micrographs. Photographs of last instars of both Comachara and Polygrammate are provided. Larval feeding and pupation habits of C. cadburyi are briefly described and compared with those of Polygrammate. Larvae of both Polygrammate and Comachara exhibit a dramatic coloration change in the last instar, transitioning from a green phase to a mottled, steely gray form. As the color change progresses, the larva ceases feeding and enters a wandering phase, during which it seeks out wood in which to pupate. Interpretation of L group setal homologies on the ninth abdominal segment is briefly addressed. Comachara provides a poignant example of the importance of immatures in elucidating phylogeny - adult features of Comachara misled a number of the twentieth century century's finest lepidopterists.

Notre recherche porte sur la théologie mystique chez Grégoire de Nysse et effectue une relecture de la mystique du Nysséen à partir de deux thématiques capitales dans l’œuvre de ce dernier : la thématique gnoséologique et la thématique érotique. Au cours de cette étude, nous montrons la place considérable de la gnôsis dans l’œuvre grégorienne et nous redéfinissons le statut de celle-ci dans l’ascension de l’âme vers Dieu en lien étroit avec l’amour. Cet amour, désigné par l’érôs, constitue le double mouvement de l’expérience mystique et se définit comme l’érôs de Dieu pour l’homme (l’incarnation du Christ) et l’érôs de l’homme vers Dieu (la divinisation de l’homme). Cette conception de l’érôs résulte à la fois d’une continuité et d’une discontinuité par rapport à l’héritage philosophique grec, dans une relation qui nous invite à redéfinir la théologie comme généalogie. À partir de cette aventure érotique entre Dieu et l’homme, Grégoire établit une relation intrinsèque entre foi et raison et pose les fondements d’un dialogue véritable entre théologie et philosophie puisque, selon lui, la véritable ascension mystique ne saurait être détachée de la démarche gnoséologique, elle-même étroitement liée à l’expérience érotique. Ainsi la mystique, fondée sur la gnôsis et l’érôs, redéfinit-elle la théologie comme mystique. / This piece of research into Gregory of Nyssa’s mystical theology provides a rereading of Gregory’s mysticism, based upon two leading themes in his work: gnoseology and eros. The study demonstrates the considerable space Gregory gives to gnôsis in his work, and redefines the role it plays in the soul’s ascent to God, which is closely connected with love. This love, designated as erôs, constitutes the dual movement of mystical experience, and is defined as the erôs of God for human beings (incarnation of Christ) and as the erôs that draws human beings towards God (divinisation of humanity). Such a conception of erôs is both continuous and discontinuous with the Greek philosophical tradition, a relation that invites a redefinition of theology as genealogy. On the basis of this erotic adventure between God and humankind, Gregory establishes an intrinsic relation between faith and reason, and lays the foundations of a genuine dialogue between theology and philosophy. For according to him, authentic mystical ascent cannot be detached from the gnoseological process, which, in turn, is closely linked to erotic experience. In this way, a mysticism founded on gnôsis and erôs leads to a redefinition of theology as mysticism.

Thesis advisor: Jane E. Regan / The Eastern Fathers through the centuries affirm that askesis—struggle and training in spiritual life—is integral to Christian growth, life, and maturity. It is a part of the Church’s basic mindset regarding growth in life in Christ. Within the US Orthodox Christian Education (OCE) field, however, no substantial treatment of this theme exists. The place of a discussion of askesis within OCE requires that one perceive how vitally and expansively the Orthodox Church understands this theme. Clearing lesser things from the heart, preparing room for divinity, learning to turn the eyes of the heart toward Christ, and to fix them on Him in all things are all vital to acquiring the Holy Spirit, whose fruit in us proclaims and brings about the Gospel of Jesus Christ. Christian witness presupposes fruit, while fruit is born of divine indwelling. Yet, as Gregory of Nyssa affirms, grace “does not naturally frequent souls which are fleeing from salvation.” We must engage. If spiritual maturity is important to the Church’s witness, then, so is developing maturity. In this way, askesis is integral to the mission of the Church. The Eastern Fathers understand this training in expansive ways. While askesis can indicate a subset of specific practices (vigils, fasting, chastity, etc.) in a larger sense it indicates active formation in spiritual life in general. Various Fathers affirm things as diverse as prayer, marriage, faith, childrearing, and patient endurance of suffering as opportunities for askesis. Since askesis is vital to Orthodox Christian life and faith, and given the gap in coverage, this study explores the theme, in three steps. First, after surveying recent OCE engagements with askesis, it considers in depth the spiritual anthropology and ascetical teaching of a relatively early figure, Gregory of Nyssa. Second, it explores three themes from the Byzantine period that display some of the Church’s broader, more settled sensibilities regarding askesis, namely, 1) the centrality of Jesus Christ in developing virtue and maturity; 2) the importance of the Church and Sacraments for spiritual growth; and 3) how material creation figures in spiritual life. Third, the study turns to the voices of more recent elders as they convey the Church’s expansive understanding of askesis. Again, three themes are developed: 1) how each and every aspect of human nature must be formed in Christ; 2) how, in God’s providence, the entire arena of life provides opportunities for Christian development; and 3) the ascetic character of an Orthodox Christian vision of education. This study is not a historical work of Christian spirituality, a history of the development of ascetical theology, or a comprehensive summary of its theme. Rather, it seeks to specify key elements of the developmental path to freedom in Christ proclaimed by the Orthodox faith, and to argue for their wisdom and fruitfulness. It aims to be a useful tool for those engaged in the task of forming the faithful. A final chapter summarizes implications in this regard. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

<p>Against the dominant contemporary options of usefulness and disinterestedness, this dissertation attempts to display that beauty is better--more fully, richly, generatively--described with the categories of fittingness and gratuity. By working through texts by Gregory of Nyssa, this dissertation fills out what fittingness and gratuity entail--what, that is, they <italic>do</italic> for beauty-seekers and beauty-talkers. After the historical set-up of the first chapter, chapter 2 considers fittingness and gratuity through Gregory's doctrine of God because Beauty, for Gregory, is a name for God. That God is radically transcendent transforms (radicalizes) fittingness and gratuity away from a strictly Platonic vision of how they might function. Chapter 3 extends such radicalization by considering beauty in light of Christology and particularly in light of the Christological claims to invisibility, poverty, and suffering. In a time when beauty is wending its way back from an academic exile enforced by its associations with the `bourgeois,' such considerations re-present beauty as deeply intertwined with ugliness and horror. Chapter 4 asks how it is a person might perceive such beauty, which calls for pneumatological and anthropological reflections on Gregory's doctrine of the spiritual senses. The person who sees beauty rightly, for Gregory, is the person who is wounded by love.</p> / Dissertation

The Late Hemphillian (latest Miocene or earliest Pliocene, 7-4.5 Ma) Gray Fossil Site in northeastern Tennessee is interpreted to represent a lacustrine paleokarst fed by a river or stream. This research focuses on the morphological and systematic relations of Nyssa endocarps (fruit pits) from the fossil site to extinct and extant Nyssa species. A combination of metric and nonmetric traits allows recognition of a new species: Nyssa grayensis sp. nov. This fossil species shares the most similarities with the extant Nyssa ogeche Bartram ex Marshall from southeast North America and the Eocene fossil Nyssa eolignitica Berry from western Tennessee. Affinities with Nyssa ogeche Bartram ex Marshall suggest a warmer winter climate than the present and periodically fluctuating water levels. Fossil vertebrates (Alligator, Heloderma, Hesperotestudo) and plants (Fossil relatives of Ilex vomitoria, Quercus virginiana, Taxodium, Acer leucoderme) with modern counterparts distributed in areas with mild winters support this interpretation.

This thesis deals with the topic of human liberty as it was developed in The Great Catechism by St. Gregory of Nyssa. It is concerned with the importance and role of liberty in the particular periods of the history of salvation (creation, fall and redemption) and with the relation between liberty and other important themes of Gregory's work: man as the image of God and as a creature composed of soul and body; the human's fall and the turn from the real good (which is God) towards evil; new life acquired from Christ's resurrection and the adoption of this new life through baptism and the Eucharist. The man was created for life in freedom; life oriented towards the real good: the God. The man cannot be really free without this orientation towards God, but on the other hand this orientation cannot exist without freedom either. God gave man the life and after the fall he returns it to him, but the acceptance and the shape of this life is at all times dependent on the man's decision. The man, as a created being, is someone who changes all the time. And it is just because he can again and again decide about these never-ending changes of himself, that he can have in his power not only his deeds, but also himself: he is his own master, as God is.

Ce travail de thèse présente la pensée de Grégoire de Nysse sur la corrélation entre le cosmos et l’homme. La recherche a pour ambition d’expliquer et de comprendre la conception grégorienne de la création et l’interprétation du rôle de l’homme dans la création pour voir si elle apporte ou non un complément potentiel au débat contemporain sur la crise écologique. Il s’avère que cette problématique contemporaine conduit à renouveler notre regard sur les textes de Grégoire et à dégager ses réflexions sur un mode de comportement envers la création, propre à sa vision théologique de Grégoire. L’analyse des concepts concernant le cosmos et l’homme démontre une bipolarité de leurs relations possibles, qui s’exprime dans l’idée d’ontologie et d’éthique cosmique. L’éthique semble alors être la liberté vécue de l’homme sur cette terre, avec pour résultat le principe agissant de son rapport avec le reste de la création au cours de sa vie. D’après Grégoire, l’approche humaine en ce qui concerne l’environnement n’est qu’une question de liberté de choix qui pourtant marque le cheminement de l’homme vers la nouvelle création, celle créée par le Christ. / This thesis presents Gregory of Nyssa’s point of view about the relation between man and the cosmos. The current analysis aims to understand and explain Gregory’s concept of creation and the way this concept perceives the role of the human in the creation; this is in order to verify if it makes any eventual addition to the contemporary debate on ecological crises. Actually, this contemporary problematic contributes in renewing our view on Gregorian texts and shows a way of behaviour towards the nature/creation itself in accordance with the theological vision of Gregory. The analysis of concepts concerning the human and the cosmos stresses a twofold relation between them, expressed through the idea of ontology and cosmic ethics. In this case ethics seem to be the experimental liberty of man on this earth and as a consequence, the active principle of the relation with the rest of the creation in the frame of life. According to Gregory, the human approach towards the environment is only a question of free will which nevertheless determines the way of man to the new creation established by Christ.
