Opus Sanctorum Angelorum

Opus Sanctorum Angelorum ('Work of the Holy Angels'), more commonly known as Opus Angelorum ('Work of the Angels'; German: Engelwerk), is a movement within the Catholic Church that promotes devotion to angels, based on the alleged private revelations of Gabriele Bitterlich.

The Holy See recognized it in 2010 as in full conformity with the Church's teaching, after a period in which controversy led to it being placed under the oversight of a Dominican priest in 1992.

It spreads devotion to the Holy Angels among the faithful, exhorts them to pray for priests, and promotes love for Christ in his Passion and union with it.

It is active particularly in Austria, where it originated, and in Germany, but also in Portugal, Brazil, Mexico, India, the Philippines, Italy and the United States.

Between 1998 and 2020 the number of members has decreased from about a million persons (including about 50 bishops and some cardinals) to some thousands worldwide.

The movement is now under the overall direction of the Order of Canons Regular of the Holy Cross, who have about 125 members, living in 12 communities in 10 countries (Austria, Italy, Germany, Portugal, Colombia, Brazil, Mexico, India, the Philippines, United States).

In canon law, the movement is classified as an association of the Christian faithful, and includes, as well as individual members, lay, religious and priests, two religious institutes, the Canons Regular of the Holy Cross and the Sisters of the Cross.
