What did Jesus mean in John 13:8 and 10?
Re: John 13:8
“Commentators have debated the meaning of Jesus’ response, ‘Unless I wash you, you have not part with me.’ The context suggests that ‘wash’ (nipto) must refer to the washing of feet, but some believe that a double meaning is present. Morris believes the words point to a ‘washing free from sin.’ Tenney interprets Jesus to refer to the need for ‘cleansing’ Peter’s personality to make him fit for the kingdom. Westcott argues that Jesus is referring to ‘self-surrender” as the first condition of discipleship. Students of Scripture must avoid such speculation and interpret the passage quite literally.“1
Re; John 3:10
“Many expositors interpret 13:10 to teach the need for confession and cleansing from sin. … Granted, there is a difference between the Greek words translated ‘washed’ and ‘bathed.’ ‘Washed’ (louo) speaks of washing the entire body, whereas ‘bathed’ (nipto) usually refers to washing a part of the body. But what logic compels the interpreter to see spiritual cleansing as the point of the passage? Although the bathing and washing imagery could well illustrate the teaching of Titus 3:5 and 1 John 1:9, spiritual cleansing from sin is not the point of this passage.”2
“A foundational principle of hermeneutics is, ‘Do not add to the interpretation when an explanation is given in the text.’ Another helpful guide is ‘Always prefer the clear meaning over an obscure interpretation.’ Applying these principles to John 13:4-11 one discovers in Jesus’ own explanation (13:12-20) that the foot washing teaches a simple but profound lesson concerning the humble service each believer ought to pursue.”3
My response:
While I am still working through the passage, I appreciate Laney’s admonition. If we are left to guess the meaning, we may come up with many interpretations. It is usually better to take the Scripture literally unless otherwise noted. Stick with what the passage is saying and you will find the meaning.
