This series of studies is not about diet or hygiene. Such matters do not lie in my area of expertise, nor do I wish to be put in a position of making public recommendations along such lines. Rather, these are studies in Biblical Theology. Because of the nature of the topic, however, the contents of these studies will be of interest to persons concerned with diet. Many readers will be looking for a statement that we ought to keep the Mosaic dietary laws for reasons of health, and these readers will be disappointed. Faithfulness to Christ—to His Scriptures primarily, and secondarily to the voice of His Spirit as He has guided the Christian Church through two millennia—compels me as a teacher and theologian to insist that the Mosaic dietary laws, as they are written, are not relevant to hygiene.
