I was recently sent a PDF of a Form of Consecration to St. Joseph. Unfortunately, there is no author listed, no date. But in looking into it further, it appears to be referenced on a few other websites.
Here is the website that give an abbreviated form of the same Consecration (and is the same sourced used by other websites as well when publishing this same Preparation for Consecration to St. Joseph).
"So let us be confident, let us not be unprepared, let us not be outflanked, let us be wise, vigilant, fighting against those who are trying to tear the faith out of our souls and morality out of our hearts, so that we may remain Catholics, remain united to the Blessed Virgin Mary, remain united to the Roman Catholic Church, remain faithful children of the Church."- Archbp. Lefebvre 1980
