Clement of Rome

“ Chapter III.—Rules for the Conduct of Celibate Brethren in Places Where There are Only Married Christians.
And if again we chance to come into a place where there is no consecrated brother, but all are married, all those who are there will receive the brother who comes to them, and minister to him, and care for his wants [1] in everything, assiduously, with good-will. ”

“ We holy men do not eat or drink with women, nor are we waited on by women or by maidens, nor do women wash our feet for us, nor do women anoint us, nor do women prepare our bed for us, nor do we sleep where women sleep, so that we may be without reproach in everything, lest any one should be offended or stumble at us. ”
