Trata-se de um estudo aprofundado e diversificado sobre o espaço litúrgico cristão, lugar de encontro da comunidade de fé com seu senhor, Jesus Cristo, Logos encarnado, visível na Palavra e no Pão e no Vinho da refeição eucarística, e expressos nos focos físicos do ambão e da mesa/altar. O estudo do tema leva, em primeiro lugar, à investigação sobre as características que devem ter um espaço físico de teofania, vinculadas aos transcendentais de Beleza, Bondade, Verdade e Harmonia, que Platão entendia como da essência divina. Busca-se entender como esses transcendentais foram observados ao longo dos tempos também no pensamento de Plotino, Agostinho, Kant e Hegel. Em seguida, de forma multidisciplinar, são apresentadas as contribuições de uma teologia da estética e dos sacramentos, em diálogo com a Filosofia, a Ética, a História, a Arquitetura, a Filosofia da Arquitetura, a Liturgia e as Santas Escrituras, nas tradições cristãs do anglicanismo, do luteranismo e do catolicismo romano. Há desdobramentos sobre a reflexão e o trabalho de arquitetos em torno da expressão concreta da imanência e da transcendência divinas na arquitetura, tentando expressar o Inexpressável, e vinculando assim a Bela Arte da Arquitetura ao campo da fé cristã. A seguir, uma exaustiva pesquisa é realizada em torno ao ambão e ao altar, focos físicos da Presença divina, interpretando- os a partir de tipologias teológicas e de sua utilização nas três denominações acima mencionadas. Finalizando, tendo como base teórica a filosofia da arquitetura e a hermenêutica filosófica de Gadamer, analisa espaços litúrgicos concretos, projetados e construídos pela arquiteta Maria Inês Bolson Lunardini, especializada em arquitetura sacra na cidade e na área metropolitana de Porto Alegre (RS). Assim o estudo teórico realizado ao longo do corpo do trabalho dialoga com um contexto concreto. A tese mostra que ambão e a mesa/altar são, no contexto do espaço sagrado onde a comunidade de fé é convocada e se congrega, o lugar da Presença viva do Logos Encarnado. / This academic work is a profound and diversified study on the Christian liturgical space, place of gathering of the community of faith with his Lord, Jesus Christ, the incarnated Logos, visible in the Word and in the Bread and Wine of the eucharistical meal, as expressed in the physical foci of the ambo and the altar/table. The consideration of the subject leads, firstly, to the research of the characteristics that the physical space of a theophany must have, entailed to the transcendentals of Beauty, Truth, Goodness and Harmony, meant by Plato as qualities of the divine essence. Attempt is made in order to understand how transcendentals were seen along history and also in the thought of Plotinus, Augustine, Kant and Hegel. Inmediately, in an multidisciplinarian way are introduced the contributions of a theology of aesthetics and sacraments in dialogue with Philosophy, Ethics, History, Architecture, Liturgy and Holy Scripture, with glimpses on the Anglican, Lutheran and Roman Catholic traditions. There are, also, an unfolding on how architects reflect and work around the concrete expressions of the divine immanence and transcendence in Architecture, trying to express the Unexpressable, and relating, in this way, the Fine Art of Architecture to Christian Faith. Following on the way, an accurate research is made on the ambo and the altar, physical foci of the divine Presence, viewing them from the point of view of theological typologies and their use in the three denominations afore said. Finally, and bearing in mind as theoretical base the philosophy of architecture and the philosophical hermeneutics of Gadamer, is made a critic of concrete liturgical spaces, designed and built by the architect Maria Ines Bolson Lunardini, specialized in sacred architecture and working in the city of Porto Alegre (RS) and its metropolitan area. In this manner, the theoretical study developed along this work dialogues with a concrete context. Thesis points out that ambo and altar/table are, in the context of the sacred space where the community of faith is summoned and gathers, the place of the living Presence of the Incarnated Logos.

Text in German / Die vorliegende Dissertation untersucht die christologischen Schwerpunkte im Leben und Denken von Frère Roger Schutz von Taizé und zeigt Querverbindungen zu unterschiedlichen theologischen Ansätzen. Dabei werden dogmatische Berührungspunkte zu den Vätern der alten Kirche, zur lutherischen, katholischen und orthodoxen Christologie dargestellt und untersucht. Als Basis der systematisch-theologischen Forschungsarbeit dienen die theologischen Studien, Tagebücher und erbaulichen Schriften, die Roger Schutz zwischen 1943 und 2005 geschrieben hat, sowie die liturgischen Hefte und Gebetsbücher von Taizé, die auf ihren christologischen Gehalt untersucht werden. Die poetische Sprache von Frère Roger erfordert eine literarische und theologische Interpretation, die mit zwei Brüdern der Gemeinschaft in Taizé besprochen wurde. Die Entwicklung der christologischen Ansichten von Roger Schutz wird durch alle Phasen seines Lebens hindurch untersucht, sodass am Schluss der Arbeit drei wichtige Thesen dargestellt werden können, die für die Zukunft von Taizé und für die christologische Diskussion im ökumenischen Umfeld interessant sind. / This present dissertation researches the christological key factors in the life and thinking of Frère Roger Schutz of Taizé and shows specific connections to different theological theories. We find several points of reference to the church fathers, the lutheran, catholic and orthodox Christology which are categorized and evaluated. As a base of this systematic research, I use the theological reflections, the diaries and the devotional books which Roger Schutz wrote between 1943 and 2005 as well as the liturgical sheets and prayer books in Taizé center. The poetic language of Frère Roger needs a literally and theological interpretation which I discussed with two Brothers of the community. The development of the christological thinking of Roger Schutz is analysed through all phases of his life, so that at the end of my research I conclude with three final observations which are interesting for the future of the community in Taizé as well as for the christological discussion in the ecumenical context. / Systematic Theology & Theological Ethics / M.
