Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
It is interesting to note that Jesus here used actual water in this washing. How could this washing of the feet make one completely and totally clean? This is a word against those who deny the working power of the Sacrament of Holy Baptism and spiritualize everything. Except one be born of water and the Spirit, he cannot enter into the kingdom of God (John 3:5). This is the actual water of the Sacrament of Holy Baptism.
