The Legion of Mary was founded by Frank Duff on September 7, 1921 in Dublin. His idea was to help Catholic laypeople fulfill their baptismal promises and be able to live their dedication to the Church in an organised structure, supported by fraternity and prayer.
The Legion of Mary has been in the Diocese of Maitland-Newcastle for over 50 years and is the largest apostolic organisation of lay people in the Catholic Church.
The work of the Legion of Mary is apostlistic by nature. Members visit homes, hospitals, jails and parish events to spread the message of peace to Catholic or non-Catholic, Christian or non-Christian.
