    The word became text and dwells among us? an examination of the doctrine of inerrancy

    No full text
    In 1978 a group of evangelical philosophers and theologians held a meeting to decide what the definitive statement on the doctrine of inerrancy would be. Drawing on the thought of B.B. Warfield and others this group came up with a statement comprising of a short statement, nineteen articles including both statements of affirmation and denial, as well as, an exposition of these articles. Taken in its entirety, this statement is intended to be the Evangelical statement determining all subsequent information about the doctrine of inerrancy. Leading evangelicals, including Carl F.H. Henry signed this document in order to establish a consensus on what one meant when using the term inerrancy. Almost three decades later this term is still used with a sense of confusion and the doctrine is no less controversial. In fact, it still is responsible for the division of departments in many evangelical institutions of higher education in North America. The following thesis hopes to help loosen this doctrine from its theological ‘stronghold’ and place it in a position where it will be less likely to cause division amongst evangelicals. By examining the thought of both B.B. Warfield, who helped create the doctrine, and Carl F.H. Henry, who played a contemporary role in the formation of the Chicago Statement and who might rightly be considered the evangelical theologian of the twentieth century, this thesis brings to light certain presuppositions of the doctrine of inerrancy that allow it take a position that undergirds other theological doctrines. By identifying the nature of truth and authority as the main tenants of the inerrantist position, the thesis examines these terms in light of the thought of both Warfield and Henry. Their thought is found to be remarkably similar to certain principles and concerns raised by Enlightenment philosophers and it is concluded that the understandings of truth and authority presupposed by the doctrine of inerrancy ultimately are biased by Enlightenment philosophy and so are an inadequate representation of the terms as used in Scripture and tradition. The thesis suggests that an adequate understanding of truth would be primarily Christological in nature and, therefore, a larger category than the one presupposed by the doctrine of inerrancy. Also, an adequate understanding of authority would presuppose the contemporary work of the Holy Spirit, which again makes for a much larger pneumatological category than the one presupposed by the doctrine of inerrancy as it is currently defined. Enlarging these categories in no way necessitates the denial of inerrancy altogether. Rather it removes the doctrine of inerrancy from its theological pedestal and places it amongst other beliefs that might support the truth and authority of Scripture but by no means establish them. The concluding chapter ends with a statement of what this new doctrine of inerrancy might look like

    Incorporation of 3 μm SiCp into Titanium surfaces using a 2.8 kW laser beam of 186 and 373 MJ m-2 energy densities in a nitrogen environment

    The formation of composite layers using a 2.8 kW laser beam of 186 and 373 MJ m−2 energy densities, on commercial purity titanium surfaces preplaced with 3 μm size, 1-4 vol.% SiCp powder in a 100% nitrogen environment, produced gold colour tracks. The tracks gave reflective surfaces after glazing at an energy density of 373 MJ m−2 and dull or a mixture of dull and shiny surfaces at 186 MJ m−2 energy density. Surface cracks were visible in tracks containing 1 and 2 vol.% SiCp, but none were observed in the 4 vol.% SiCp tracks glazed at both energy densities. In the track cross sections, vertical cracks were seen in the 373 MJ m−2 tracks but it was absent in 186 MJm−2 tracks. The SiCp particles completely dissolved in all the tracks processed in this investigation producing a complex and inhomogeneous microstructure of dendrites and needle particles. At the half way of the melt depth from the surface, the dendrites were larger and densely populated, especially after glazing at 373 MJ m−2. The hardness measurement of the MMC layer recorded a wide range of hardness values which gave loops in the hardness profiles. Hardness values ranging from 700 to 1000 Hv were observed up to a melt depth of 1 mm in many tracks and the maximum surface hardness of 2250 Hv was measured in the track containing 1 vol.% SiCp and glazed at 373 MJ m−2. The surface hardness developed 5.6-15 times the base hardness (150 Hv) depending on the dendrite population. The 3 μm size SiCp produced MMC layers 1.5-2 times greater than those previously observed with 6 μm SiCp. The large surface area for an equivalent volume fraction of the three micron carbide particles is considered to have a high laser coupling action and hence absorbed more heat energy to produce deeper melt depth compared to those produced using the 6 μm SiCp

    The Midgut Of Cephalotes Ants (formicidae: Myrmicinae): Ultrastructure Of The Epithelium And Symbiotic Bacteria

    No full text
    The ultrastructural analysis of the midgut of Cephalotes atratus, C. clypeatus, and C. pusillus reveled that the midgut epithelium lays on a basal lamina and is composed basically of three cell types: digestive cells, regenerative cells, and goblet cells. In these ants, the rough endoplasmic reticulum, in addition to producing digestive enzymes, is involved in the formation of concretions and ion storage in specialized vacuoles present in the midgut. These concretions are spherocrystals and may contribute to stabilize the pH and to maintain symbiotic bacteria found between microvilli. The ultrastructure analysis of these bacteria revealed the presence of a double envelope typical of gram-negative bacteria. For the three species examined, the ultrastructure similarities are conspicuous, suggesting that this may be the pattern for the genus Cephalotes. Details of the relationship between bacteria and microvilli were examined. © 2010 Elsevier Ltd.415448454Arab, A., Caetano, F.H., Functional ultrastructure of the midgut of the fire ant Solenopsis saevissima Forel 1904 (Formicidae: Myrmicinae) Cytobios (2001) Cambridge, 105, pp. 45-53Baumann, P., Baumann, L., Lai, C.Y., Rouhbahsh, D., Moran, N.A., Clark, M.A., Genetics, physiology, and evolutionary relationship of the genus Buchnera: intracellular symbionts of the Aphides (1995) Annu.
