Here is a footwashing prayer from Origen, a church leader from the third century.
O Jesus, my feet are dirty.
Come even as a slave to me,
pour water into your bowl,
come and wash my feet.
In asking such a thing I know I am overbold
but I dread what was threatened when you said to me,
“If I do not wash your feet I have no fellowship with you.”
Wash my feet then, because I long for your companionship.
And yet, what am I asking?
It was well for Peter to ask you to wash his feet,
for him that was all that was needed for him to be clean in every part.
With me it is different:
though you wash me now I shall still stand in need of that other washing,
the cleansing you promised when you said,
“there is a baptism I must needs be baptized with.”
~ Origen c. 185-c. 254
