From Becoming Fire: Through the Year with the Desert Fathers and Mothers
Washing the feet of evildoers
It was said of Abba John the Persian that when some evildoers came to him, he took a basin and wanted to wash their feet. But they were filled with confusion, and began to do penance.
Washing Christ’s feet
One time, while Abba Bishoy was praying in his cave, the savior visited him with two angels, as he had the patriarch Abraham, (Genesis 18), and said, “Greetings Bishoy! Today we will be enjoying your hospitality if you oblige and welcome us.”
Bishoy eagerly welcomed them, emulating the hospitality of that patriarch. He did not busy himself with food and drink, however, but rather possessed a pure disposition. So he welcomed the Omnipresent One; then, putting water in a basin, he washed your undefiled feet in imitation of you.” (John 13:1-11) It happened this way: Bishoy eagerly busied himself with showing hospitality while the Lord, demonstrating his love for humankind, accepted his hospitality. (Nothing that a person does in offering hospitality shows more kindness and forbearance than to wash the feet of those who come to visit.)
“Peace be with you, my chosen one,” (John 14:27), said the savior, and then he disappeared.
