While foot-washing1 has possessed a negligible presence among Southern Baptists since our actual founding in 1845, its practice may nonetheless be found among some individual congregations affiliated with the SBC >>>
Presently, I'm teaching through Article VII in The Baptist Faith and Message dealing with our two church ordinances. Baptism and the Lord's Supper. I found the following quote by a longtime favorite author, Francis Schaeffer, particularly insightful:
While most of us think it is a mistake to make this a sacrament, let us admit that it is 10,000 times better to wash each other’s feet in a literal way than never to wash anybody’s feet in any way. It would be far better for us to make a mistake and institute a third sacrament of literal foot-washing than to live out our lives without once consciously choosing to serve each other. Doing the Lord’s work in the Lord’s way is not some exotic thing; it is having and practicing the mentality which Christ commands.2
Schaeffer is surely correct. While those who practise foot-washing may not have sufficient biblical warrant upon which to claim the practice as an ordinance of the church, it is mistaken to think not washing anybody's feet in any way is better than, without sufficient biblical warrant, washing others feet in a literal way.
1the common biblical basis cited for practicing foot-washing is John 13: 1-17. Many Free-will Baptists, Primitive Baptists, and other independent Baptist congregations still observe the ritual, some claiming it as a third ordinance of the church. Historically, Separate Baptists and General Baptists routinely practiced foot-washing. Beginning in 1925, no Southern Baptist confession acknowledged any church ordinance other than Baptism and the Lord's Supper.
