John 13:14

Verses 14,15. Ye also ought to wash, &c. Some have understood this literally as instituting a religious rite which we ought to observe; but this was evidently not the design; for, 1st. There is not evidence that Jesus intended it as a religious observance, like the Lord's Supper or the ordinance of baptism. 2nd. It was not observed by the apostles or the primitive Christians as a religious rite. 3rd. It was a rite of hospitality among the Jews, a common, well-know thing, and performed by servants. 4th. it is the manifest design of humility; to teach them by his example that they ought to condescend to the most humble offices for the benefit of others.
