The following from piusbruderschaft.de, the German Province website of the SSPX:
On the 19th of March the Society will officially consecrated to St. Joseph. As a preparation for this important event pius.info has published texts and prayers to the great patron of the Church, so that the priests and faithful might correspondingly prepare.
Read the documents of Pius IX. and Leo XIII about St. Joseph.
As almighty God appointed Joseph, son of the patriarch Jacob, over all the land of Egypt to save grain for the people, so when the fullness of time was come and He was about to send to earth His only-begotten Son, the Savior of the world, He chose another Joseph, of whom the first had been the type, and He made him the lord and chief of His household and possessions, the guardian of His choicest treasures.
Indeed, he had as his spouse the Immaculate Virgin Mary, of whom was born by the Holy Spirit, Jesus Christ our Lord, who deigned to be reputed in the sight of men as the son of Joseph, and was subject to him.
Him whom countless kings and prophets had desired to see, Joseph not only saw but conversed with, and embraced in paternal affection, and kissed. He most diligently reared Him whom the faithful were to receive as the bread that came down from heaven whereby they might obtain eternal life.
Because of this sublime dignity which God conferred on his most faithful servant, the Church has always most highly honored and praised blessed Joseph next to his spouse, the Virgin Mother of God, and has besought his intercession in times of trouble.
And now therefore, when in these most troublesome times the Church is beset by enemies on every side and is weighed down by calamities so heavy that ungodly men assert that the gates of hell have at length prevailed against her, the venerable prelates of the whole Catholic world have presented to the Sovereign Pontiff their own petitions and those of the faithful committed to their charge, praying that he would deign to constitute St. Joseph Patron of the Church. And this time their prayer and desire was renewed by them even more earnestly at the Sacred Ecumenical Council of the Vatican.
Leo XIII (1878-1903)
Excerpt from the Encylcical Quamquam pluries, 15 August 1889
Although We have already many times ordered special prayers to be offered up in the whole world, that the interests of Catholicism might be insistently recommended to God, none will deem it matter for surprise that We consider the present moment an opportune one for again inculcating the same duty. During periods of stress and trial - chiefly when every lawlessness of act seems permitted to the powers of darkness - it has been the custom in the Church to plead with special fervour and perseverance to God, her author and protector, by recourse to the intercession of the saints - and chiefly of the Blessed Virgin, Mother of God - whose patronage has ever been the most efficacious. The fruit of these pious prayers and of the confidence reposed in the Divine goodness, has always, sooner or later, been made apparent. Now, Venerable Brethren, you know the times in which we live; they are scarcely less deplorable for the Christian religion than the worst days, which in time past were most full of misery to the Church. We see faith, the root of all the Christian virtues, lessening in many souls; we see charity growing cold; the young generation daily growing in depravity of morals and views; the Church of Jesus Christ attacked on every side by open force or by craft; a relentless war waged against the Sovereign Pontiff; and the very foundations of religion undermined with a boldness which waxes daily in intensity. These things are, indeed, so much a matter of notoriety that it is needless for Us to expatiate on the depths to which society has sunk in these days, or on the designs which now agitate the minds of men. In circumstances so unhappy and troublous, human remedies are insufficient, and it becomes necessary, as a sole resource, to beg for assistance from the Divine power.
You well understand, Venerable Brethren, that these considerations are confirmed by the ,opinion held by a large number of the Fathers, to which the sacred liturgy gives its sanction, that the Joseph of ancient times, son of the patriarch Jacob, was the type of St. Joseph, and the former by his glory prefigured the greatness of the future guardian of the Holy Family. And in truth, beyond the fact that the same name - a point the significance of which has never been denied - was given to each, you well know the points of likeness that exist between them; namely, that the first Joseph won the favour and especial goodwill of his master, and that through Joseph's administration his household came to prosperity and wealth; that (still more important) he presided over the kingdom with great power, and, in a time when the harvests failed, he provided for all the needs of the Egyptians with so much wisdom that the King decreed to him the title "Saviour of the world." Thus it is that We may prefigure the new in the old patriarch. And as the first caused the prosperity of his master's domestic interests and at the same time rendered great services to the whole kingdom, so the second, destined to be the guardian of the Christian religion, should be regarded as the protector and defender of the Church, which is truly the house of the Lord and the kingdom of God on earth. These are the reasons why 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 earn 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.
Through these considerations, the poor and those who live by the labour of their hands should be of good heart and learn to be just. If they win the right of emerging from poverty and obtaining a better rank by lawful means, reason and justice uphold them in changing the order established, in the first instance, for them by the Providence of God. But recourse to force and struggles by seditious paths to obtain such ends are madnesses which only aggravate the evil which they aim to suppress. Let the poor, then, if they would be wise, trust not to the promises of seditious men, but rather to the example and patronage of the Blessed Joseph, and to the maternal charity of the Church, which each day takes an increasing compassion on their lot.
