The Pope saluted the group today after he led pilgrims in praying the midday Angelus.
The institution was founded in 1963 by Spanish-born Mother Trinity of the Holy Mother Church. The Holy See in 1997 declared it an institution of pontifical right.
The Work, in which priests, lay people, consecrated and non-consecrated individuals, married couples, young people, and children participate, has opened more than 40 houses in several continents. It has more than 2,000 members, including 80 priests.
Its principal charism is the spreading of love in the Church of Christ, based on a theological mystical experience.
Mother Trinity has given thousands of talks, recorded to make 700 tapes and 300 videos, and published into three books: “The Church and Its Mystery,” “Fruits of Prayer” and “Experiences of the Soul.”
Mother Trinity, who is sick, has lived in Rome for years. On Dec. 15, 1996, John Paul II visited her and blessed her in her own room.
