The Legion of Mary is an association of Catholics who, with ecclesiastical approval, have formed a Legion to serve the Church.

In 1928 the Manual of the Legion of Mary was written, which is a kind of photograph of the Movement in which one can see what had been put into practice for a long time.

The new edition of the Legion of Mary Manual is out, every legionary should get a copy as soon as possible. In addition to the wealth of material provided since previous editions, the Manual contains new Church teachings, modern scriptures, and new material.
