From the USCCB:
The fourteen days from June 21—the vigil of the Feasts of St. John Fisher and St. Thomas More—to July 4, Independence Day, are dedicated to this “fortnight for freedom”—a great hymn of prayer for our country. Our liturgical calendar celebrates a series of great martyrs who remained faithful in the face of persecution by political power—St. John Fisher and St. Thomas More, St. John the Baptist, SS. Peter and Paul, and the First Martyrs of the Church of Rome. Culminating on Independence Day, this special period of prayer, study, catechesis, and public action will emphasize both our Christian and American heritage of liberty. Dioceses and parishes around the country have scheduled special events that support a great national campaign of teaching and witness for religious liberty.
The Fortnight for Freedom is a powerful nationwide campaign launched by our Catholic Bishops. They are asking you and me to pray, study and engage in civil and responsible public action. The Fortnight is in direct response to the notorious HHS mandate that would compel all Catholic hospitals, charities and schools — and all private businesses — to provide health services in direct contradiction to Church teaching on human life.
As Archbishop Dolan of New York powerfully stated: “Religious freedom is under attack, and we will not cease [in] our struggle to protect it.”
