JOHN PIPER: THE MAKING OF A CHRISTIAN HEDONIST Justin Gerald Taylor, Ph.D. The Southern Baptist Theological Seminary, 2015 Chair: Dr. Michael A. G. Haykin This dissertation on noted pastor and author John Piper (1946- ) constitutes an early effort in the field of intellectual biography, tracing four key influences--in roughly chronological order--upon Piper's life and theology. Those with primary influence in Piper's formative years were his parents, William S. H. Piper (1919-2007) and Ruth Mohn Piper (1918-1974), who exhibited a unique combination of joyful fundamentalism. Piper's next major influence was C. S. Lewis (1898-1963), discovered during his undergraduate studies at Wheaton College, who introduced him to romantic rationalism. Piper's first teacher at Fuller Seminary was Daniel P. Fuller (1925- ), a hermeneutics professor who planted the seeds of Christian hedonism and who gave him a love for exegetical biblicism. It was during these seminary days and into his time of doctoral study that Piper discovered Jonathan Edwards (1703-1758), whose affectional Calvinism would go on to shape Piper's theology more than anyone else. Piper's three primary venues of ministerial vocation--teaching, preaching, and writing--are all examined to reveal the ways in which each of these influencers played various roles in Piper's development of Christian hedonism and his distinct contribution to a theology of the Christian life. The dissertation concludes with two applications of the foregoing analysis, exploring how Piper uses Scripture and how he appropriates church history for pastoral ends. Also included is a comprehensive bibliography of Piper's published works (1971-2015).

Piper gaudichaudianum Kunth é uma planta da família Piperaceae, que se desenvolve abundantemente em toda a Mata Atlântica, sendo popularmente conhecida como pariparoba, jaborandi ou iaborandi. Na medicina popular suas raízes frescas são mastigadas e utilizadas como antiflamatório no alívio de dores de dente e contra distúrbios hepáticos. Um dos componentes mais estudados desta planta é o óleo essencial, cujas análises fitoquímicas revelaram o (E)-nerolidol como um dos compostos majoritários. No presente estudo, foram avaliadas as propriedades citotóxicas e mutagênicas, bem como investigados os mecanismos de citotoxicidade do óleo essencial de P. gaudichaudianum e de seu componente majoritário nerolidol, utilizando diferentes linhagens de Saccharomyces cerevisiae. Foram empregadas linhagens de S. cerevisiae deficientes em genes de reparo para excisão de bases (BER), excisão de nucleotídeos (NER), recombinação homóloga (HR), recombinação não-homóloga (NHEJ), reparo pós-replicativo (PRR) e síntese translesão (TLS). A influência do sistema redox foi avaliada em linhagens de S. cerevisiae deficientes em superóxido dismutase e/ou catalase. Os resultados dos tratamentos das linhagens XV185-14c e N123 de S. cerevisiae demonstram que, tanto o óleo essencial de P. gaudichaudianum, quanto o nerolidol induzem citotoxicidade de maneira dose dependente, sendo essa citotoxicidade mais pronunciada nos tratamentos com nerolidol. Nas avaliações de mutagênese o óleo essencial induziu efeito mutagênico na linhagem XV185-14c na concentração mais alta, entretanto o nerolidol não induziu qualquer tipo de efeito mutagênico. Os ensaios com as linhagens de S. cerevisiae proficientes e deficientes em reparo revelaram um importante papel da via BER no efeito citotóxico, tanto para os tratamentos com óleo essencial, o qual induziou uma grande sensibilidade na linhagem deficiente na DNA glicosilase Ntg2, quanto para o nerolidol, que induziu sensibilidade nas mutantes para a endonuclease Apn1 e glicosilase Ntg1. Curiosamente, linhagens deficientes em TLS e PRR não apresentaram sensibilidade aos tratamentos com o óleo essencial de P. gaudichaudianum, entretanto os simples mutantes rev1, rad30 e rad18 demonstraram notável resistência ao nerolidol. Além disso, verificou-se em linhagens deficientes na enzima superóxido dismutase (sod1 e sod2) um aumento de sensibilidade nos tratamentos com o óleo essencial e com o nerolidol. No ensaio de detecção de radicais livres, por 2’7’-diclorofluoresceína (DCFH-DA), verificou-se que ambos tratamentos induzem aumento de espécies reativas de oxigênio. Considerando a resposta das diferentes linhagens de S. cerevisie utilizadas neste estudo, o conjunto destes resultados leva-nos a sugerir que tanto o óleo essencial quanto o nerolidol não são mutagênicos e que a citotoxicidade induzida pelo óleo essencial está relacionada com a formação de lesões oxidativas, sendo o nerolidol o principal responsável pelos efeitos biológicos induzidos pelo óleo essencial de P. gaudichaudianum. / Piper gaudichaudianum Kunth is a plant of the Piperaceae family, which develops abundantly throughout the Atlantic Forest, popularly known as pariparoba, jaborandi or iaborandi. In popular medicine the fresh roots are chewed and used as antinflamatory to relief of toothaches, and against liver disorders. One of the most studied components of the plant is the essential oil, which the phytochemical analysis revealed (E)-nerolidol as major compound. In the present study, we have evaluated the cytotoxicity and mutagenicity, as well as investigated the mechanism of cytotoxicity of essential oil of P. gaudichaudianum and its major component nerolidol using different strains S. cerevisiae. Strains deficient in DNA repair mechanisms such as base excision repair (BER), nucleotide excision repair (NER), homologous recombination (HR), non-homologous end joining (NHEJ), post-replication repair (PRR) and translesion synthesis (TLS) were employed. The influence of the redox system was evaluated in superoxide dismutase and/or catalase defective strains. The results of treatment of XV185-14 and N123 S. cerevisiae strains demonstrated that the essential oil and nerolidol induced cytotoxicity in a dose dependent manner, and this cytotoxicity is more pronounced with nerolidol treatments. In the mutagenicity assay only P. gaudichaudianum essential oil, but not nerolidol was able to induce mutagenic effect at highest concentration in XV185-14c strain. Employing S. cerevisiae strains proficient and deficient in DNA repair treated with P. gaudichaudianum essential oil and neroliodol, it was observed an important role of the BER pathway in the cytotoxic response, since the essential oil induced a great sensitivity in strain deficient in DNA glycosylase Ntg2, and nerolidol in mutants deficient in Apn1 endonuclease and glycosylase Ntg1. Interestingly, deletion of TLS and PRR proteins had no influence on sensitivity to the essential oil, however single mutants rev1, rad30 and rad18 exhibited a remarkable resistance to nerolidol. Besides, the absence of superoxide dismutase enzyme increases the sensitivity to essential oil and nerolidol. In the 2`,7`-dichlorofluorescin (DCFH-DA) assay for detection of free radical generation, both treatments were able to increase ROS production. Considering the response of the different S. cerevisiae strains used in this study, our results demonstrate that P. gaudichaudianum essential oil and its major compound nerolidol are not mutagenic but do induce significant cytotoxic effects in S. cerevisiae that might be related to ROS generation. The cytotoxicity observed is mainly related to the generation of oxidative lesions. Moreover, nerolidol is the major compound responsible for the biological effects induced by P. gaudichaudianum essential oil.

This dissertation examines sermon application in the doctrinal preaching of John Piper. The work argues that Piper’s use of application is characterized by multifaceted purpose and the qualities of consistency, creativity, clarity, recurrence, cumulative and/or climactic effect, and contextualization. The critical model utilized involves three primary components: quality, purpose, and doctrine. A representative sample of 700 sermons is analyzed, spanning Piper’s thirty-plus years in the pulpit. Chapter 1 clarifies the thesis, presents an overview of the dissertation’s methodology, and provides research delimitations and background information. Attention is given to the motivations behind the research and the importance of the study. Chapter 2 presents biographical material so that the reader may better understand and appreciate Piper’s practice in the pulpit. His identity as a person, pastor-theologian, and preacher is explored. Chapter 3 addresses the process of study, surveying selected literature on doctrinal preaching and sermon application. Key terms such as doctrinal preaching and sermon application are defined. Moreover, the vital connection between doctrinal preaching and sermon application is demonstrated. Chapter 4 discusses the study’s methodology and describes in detail both the object and method of analysis. The critical model employed, which guided the research, is thoroughly discussed, including the six qualities of sermon application (consistency, creativity, clarity, recurrence, cumulative and/or climactic effect, and contextualization), the four purposes of sermon application (duty, character, goals, and discernment), and the doctrines applied. Chapter 5 presents a segregated analysis of Piper’s preaching utilizing the critical model described in chapter 4. Research findings are thoroughly discussed, in terms of the six qualities, four purposes, and doctrines applied. Chapter 6 presents an integrated analysis of Piper’s doctrinal preaching. Patterns of quality, purpose, doctrine, and co-occurrence are emphasized. Also, the interplay of quality, purpose, and doctrine is demonstrated. Furthermore, development over time and across select sermon series is assessed. Chapter 7 concludes the project, presenting a summary of findings, key insights, major implications, and suggestions for future research. Defining characteristics of Piper’s method are outlined, specifically in terms of the six qualities, the four purposes, and the doctrines applied.

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / This work describes the phytocemical investigation of the extracts from roots of Piper divaricatum (Piperaceae), and, the volatile chemical composition of the essential oils Schinus terebinhtifolius Raddi (Anacardiaceae). The chemical investigation of the extracts of P. divaricatum, using classic methods of chromatography on sÃlica gel, yelded an amide, (2E,4E)-pentadienamide, 5-(1,3-benzodioxol-5-yl)-N-(2-methylpropyl)- (piperlonguminine), and two benzoic acid derivatives , 3,4-dy-hidroxy- 5-(2âE,6âZ,10âE)-7â-(hydroxymethyl)-3â,11â,15â-trimethyl-hexadeca-2â,6â,10â,14â- tetraenyl), and the Ãcid 3,4-dyhydroxy-5-(2âE,6âE,10âE)-3â,7â,11â,15â- tetramethylhexadeca-2â,6â,10â,14â-tetraenyl) benzoic, this being reported for the first time in the literature. The structures of all isolated compounds were elucidated by spectroscopic methods, such as ME, IR and INMR, including 1D and 2D experimentals NMR spectroscopy and, comparison with published data for closely related compounds. The chemical composition of the essential oils from leaves of Schinus terebinthifolius , was analyzed by CG-MS and GC-FID. Fourteen components of plant 1, representing an average of more than 81.0% of the chemical compositions of the oils, were identified and eight compounds of plant 2, representing more than 98,0% in average. Both oils showed higher concentrations of monoterpenoids, but they showed different chemical compositions, whereas cis-ocimene (52%) and Ã-ocimene (19%) were major constituents of plant 1, while limonene (93%) is the major component of plant 2. / Este trabalho descreve a investigaÃÃo fitoquÃmica dos extratos das raÃzes de Piper divaricatum (Piperaceae), bem como a composiÃÃo quÃmica volÃtil dos Ãleos essenciais das folhas da espÃcie diÃica Schinus terebinhtifolius Raddi (Anacardiaceae). Foram realizadas duas coletas de P. divaricatum em locais e perÃodos distintos e o estudo quÃmico dos extratos, utilizando tÃcnicas clÃssicas de cromatografia em gel de sÃlica, resultou no isolamento de uma amida com atividade citotÃxica anti-tumoral em cÃlulas de sarcoma 180, (2E,4E)-5-(1,3-benzodioxol-5-il)-N-(2-metilpropil)-2,4- pentadienamida (piperlonguminina) da primeira coleta e dois derivados do Ãcido benzÃico: Ãcido-5-(2âE,6âZ,10âE)-3â,11â,15â-trimetil-hexadeca-2â,6â,10â,14â-tetraenil) 3,4-di-hidroxi-7â-(hidroximetil)-benzÃico, inÃdito na literatura, e o Ãcido 5- (2âE,6âE,10âE)-3â,7â,11â,15â-tetrametil-hexadeca-2â,6â,10â,14â-tetraenil)-3,4-dihidroxi benzÃico na segunda coleta. A determinaÃÃo estrutural dos compostos isolados baseouse em tÃcnicas espectroscÃpicas tais como: espectro de massa, espectro de infravermelho e ressonÃncia magnÃtica nuclear de 1H e 13C uni e bidimensionais. A composiÃÃo quÃmica dos Ãleos essenciais das folhas de dois indivÃduos de S. terebinthifolius, uma espÃcie diÃica (planta 1 = macho; planta 2 = fÃmea) foi analisada por CG/EM e CG/DIC. Para a planta 1, um total de 14 compostos foram identificados, representando em mÃdia mais que 81% da composiÃÃo quÃmica dos Ãleos , enquanto que para a planta 2 foram identificados 8 compostos, representando em mÃdia mais de 98% da composiÃÃo dos Ãleos. Os mesmos mostraram composiÃÃes quÃmicas distintas com grandes concentraÃÃes de monoterpenos, sendo o cis-ocimeno (52%) e o Ãocimeno (19%) os componentes majoritÃrios da planta 1, e o limoneno (93%) o constituinte principal dos Ãleos da planta 2.
