Caryll Houselander - quote - Christian service

I use this quote in my homily for Wednesday, January 10, about Christian service.  

Caryll Houselander, a lay Roman Catholic ecclesiastical artist, mystic, religious writer and poet, wrote this about Christian service: “We could scrub the floor for a tired friend, or dress a wound for a patient in a hospital, or lay the table and wash up for the family; but we shall not do it in martyr spirit or with that worse spirit of self-congratulation, of feeling that we are making ourselves more perfect, more unselfish, more positively kind. We shall do it just for one thing, that our hands make Christ's hands in our life, that our service may let Christ serve through us, that our patience may bring Christ's patience back to the world.”
