Joseph, of royal blood, united by marriage to the greatest and holiest of women, and reputed the father of the Son of God

Men of every rank and country should fly to the trust and guard of the blessed Joseph. Fathers of families find in Joseph the best personification of paternal solicitude and vigilance; spouses a perfect example of love, of peace, and of conjugal fidelity; virgins at the same time find in him the model and protector of virginal integrity. The noble of birth will learn of Joseph how to guard their dignity even in misfortune; the rich will understand, by his lessons, what are the goods most to be desired and won at the price of their labour. As to workmen, artisans, and persons of lesser degree, their recourse to Joseph is a special right, and his example is for their particular imitation. 

For Joseph, of royal blood, united by marriage to the greatest and holiest of women, reputed the father of the Son of God, passed his life in labour, and won by the toil of the artisan the needful support of his family. It is, then, true that the condition of the lowly has nothing shameful in it, and the work of the labourer is not only not dishonouring, but can, if virtue be joined to it, be singularly ennobled. Joseph, content with his slight possessions, bore the trials consequent on a fortune so slender, with greatness of soul, in imitation of his Son, who having put on the form of a slave, being the Lord of life, subjected himself of his own free-will to the spoliation and loss of everything.
