Footwashing is a powerful symbolic response to the Word, dramatizing the servant-hood of Jesus, both on the night before His death, and His continuing presence in our midst.
The alternative title for this day, Maundy Thursday, recalls the new commandment (mandatum novum in Latin) that Jesus gave the disciples, i. e. to love one another. See the Scripture verse I have quoted in our benediction.
May God direct each pastor of our Pentecostal Holiness Churches to follow the leading of the Holy Spirit and the Word of God on this day.
