Non SDA sources that affirm the relevance of clean and unclean meat for a Christian

Reformed Methodist, known as Wesley Synod, “They stand fully in the Wesleyan tradition because at one time John Wesley was a seventh-day Sabbath keeper and believed in keeping the dietary laws…. this information is not found in later biographies of Wesley's life but can be found in earlier books.”1

Seventh Day Baptists, “Some follow what they believe to be the biblical guidelines for healthy living by abstaining from unclean meats.”2

United Church of God, “We believe that those meats that are designated "unclean" by God in Leviticus 11 and Deuteronomy 14 are not to be eaten.”3 (Source: ucg.org/fundamental-beliefs).

* Note: The law of clean and unclean is generally taught by many different Sabbath churches, including apostolic/pentecostal Sabbath churches which still adhere to it.

Rousas John Rushdoony (1916-2001) was a Calvinist philosopher, historian, and theologian and is widely credited as the father of Christian Reconstructionism and an inspiration for the modern Christian homeschool movement. In his effort to convince his readers that the dietary laws are valid for today, He says this about Acts 10:  “Acts 10 is commonly cited as abolishing the old dietary restrictions.  There is no reason for this opinion.  Peter’s vision did not instruct him to eat pork, dogs, cats, or the like:  it prepared him for the coming of Cornelius’ servants.  The Gentiles were to be received into the kingdom…Peter did not see the meaning of the vision as a permission to eat forbidden foods…There is no evidence in the chapter that the vision had anything to do with diet; it did have everything to do with the Great Commission and the admission of Gentiles into the kingdom.” - (R.J. Rushdoony, "Institutes of Biblical Law", Vallecito, CA 1999, p.301)

Joel Scott Osteen, Evangelical Charismatic Christian, an American author, televangelist, and the senior pastor of Lakewood Church in Houston, Texas. In one of his sermons, Pastor Osteen cites scripture as telling us that it is not healthy to eat pigs and shellfish as they are unclean. He points out that these creatures are scavengers who clean up “garbage,” but biblically-permissible animals such as cattle, lamb, buffalo, poultry and various fish have different diets and digestive systems which make their flesh safe to eat (check out the link for yourself: http://www.youtube.com/watch?v=LJrJkFBEt_c).
