172. (XIII.) Charity in Servants. Servants, as well as masters, become charities, that is, angels, when they look to the Lord and shun evils as sins, and perform the duties of a servant sincerely, justly, and faithfully. Their duties, which are special and continual goods of charity, are, to attend on their masters, to wish well to them, to speak no ill of them, to act as uprightly in their absence as in their presence, and not to scorn to serve. For everyone, in whatever degree of dignity, ought to serve. Even a king should serve the Lord. And so far as anyone serves faithfully he is loved and led of the Lord. And so far as anyone looks to the Lord and shuns evils as sins, he serves freely, and not by compulsion.
