It is impossible to give a definitive or authoritative account of the purpose of SR. SRScriptural Reasoning is first and foremost a practice, and individuals and communities may engage in a practice for many and various reasons, while furthermore the purposes or agendas in SR of some practitioners have been contested or rejected by others. Moreover, the actual effects of a practice may outstrip the intentions of its practitioners. Thus Scriptural Reasoners frequently emphasize that doing and experimenting with SR as a practice logically precedes theoretical accounts of its grounds or function. According to Nicholas Adams, 'Scriptural reasoning is a practice which can be theorised, not a theory which can be put into practice. More accurately, it is a variety of practices whose interrelations can be theorised to an extent, but not in any strong sense of fully explanatory theory.'<ref>{{Harvnb|Adams|2006|p=387}}</ref> Peter Ochs makes the same point with reference to a [[midrash]] on Exodus 24:7 in b. Shab. 88a:<blockquote>In the book of Exodus, when Moses tried to deliver the Ten Commandments for the second time, the Israelites respond with the declaration ''naaseh v'nishmah!'' Literally, their declaration means "We shall do it and understand it," but, it was more likely an idiomatic expression for "We are on the job!" or "Consider it done!" The later rabbinic sages offered a homiletic rereading: "We shall first act and then understand"...We have nurtured SR in the same fashion, seeking to experiment with many forms of practice before discovering the one that best fits our goals and working over many years to refine it. We proceeded through experimentation first and only later through theoretical reflection.<ref>{{Harvnb|Ochs|2019|p=2}}</ref></blockquote>
Nevertheless, it is possible to distinguish three commonly-cited and not mutually-exclusive purposes.
