Speaking in Spanish from the window of his study at midday today, the Pope exhorted the members to profess their faith "in the Most Holy Trinity, glorifying with your words and actions, the Father, the Son and the Holy Spirit."

The Work was founded in 1963 by Spanish-born Mother Trinidad. In 1997 the Holy See declared it an institution of pontifical right.

This institution, which comprises priests, lay people, consecrated and non-consecrated individuals, married couples, young people, and children, has opened more than 40 houses in several continents. It has more than 2,000 members.

Its principal charism, based on a theological mystical experience, is the spreading of love in the Church.

Mother Trinidad has given thousands of talks, recorded in 700 tapes and 300 videos and published in three books.

The founder, who is sick, has lived in Rome for years. On Dec. 15, 1996, Pope John Paul II visited her and blessed her in her own room.
