Great questions, Chap.
The archetypal "testimony" in early Mormonism was the testimony of the Book of Mormon witnesses, though this was superseded in the early 20th century by Joseph Smith's 'First Vision' experience/report.
You may be interested in the paper I gave at this August's SLC Sunstone Symposium titled "Making Witnesses." It examines the Book of Mormon for sources of its peculiar power as a religious (and especially conversion) text, and locates in that work the roots of the present day LDS "culture of witness," as I term it, including the ritual bearing of testimony.
The recording is available through the Sunstone website. I think they charge $4 for the download.
If you do give it a listen and have any feedback, please drop me a line. This paper is a work in progress, and I'd be interested in any criticism or ideas, particularly from someone who has been thinking about related issues.
The three and eight witnesses are still used by the Church as witnesses, as is the First Vision. None of this, however, bears directly upon the phenomena of personal testimony, which is independent of the witness of others.
Unfortunately, the attempt to perceive the nature of the Restored Church through a strictly naturalistic filter is doomed to the most inexorable failure. Our perception of the world is, as always, conditioned by the perceptual filters,or perceptual
transducers (theoretical, paradigmatic, socio-cultural/intellectual templates) through which we perceive it. Assuming a purely sociological and anthropological origin of the Church will, of course, provide one with precisely that; the evidence will accumulate in that direction. Historical and Anthropological studies are indeed among those subjects in the humanities and social sciences that, by their very nature, are relatively data poor and of necessity theory, speculation, and wishful thinking rich. If the Church is more than an anthropological or sociological phenomena, then neither Anthropology or Sociology are competent to discern and comprehend those elements. But how does the philosophical naturalist and materialist know, through a strictly naturalistic perceptual filter, where the purely sociological ends and the spiritual begins (and let us assume, at least provisionally, that the spiritual may exist)?
If the preassumption is that no spiritual realities exist
a priori, then is it not the case that this is precisely where the perceptual range of the filter ends?
In other words, the limit of your intellectual paradigm is the limit of your perception, and the limit of your perception defines the boundary of your mental and cognitive world; the boundary of both critical thought and imagination.
The face of sin today often wears the mask of tolerance.
