Saint Michael’s Media, of which my DH and I are significant supporters, has a very strong devotion to Saint Michael. And in a response to this, The Legion of Saint Michael was created.
From the website:
The Legion of Saint Michael is a lay Catholic organization whose membership is open to anyone in like mind with the teachings of the Catholic Church. Its purpose is to unite the faithful in prayer, lead members to deeper holiness, and to support the efforts of Saint Michael’s Media, which is committed to overcoming the darkness in the secular media.
The Legion of Saint Michael claims as its patron Saint Michael the Archangel, the Prince of the Heavenly Hosts, champion of the Church Militant and defender of the one Holy Catholic and Apostolic Church. Its patroness is Our Lady, the Blessed Virgin Mother of Jesus Christ. Together they form an invincible shield against the powers of darkness, and can always be counted on for assistance in spiritual battle.
Members of the Legion are called to participate in the spiritual war which is “not against flesh and blood, but . . . against the rulers of the darkness of this world, against spiritual wickedness in high places.” (Ep 6:12) Taking the actions and mandate of the Archangel as our pattern and model, we seek to fight against and vanquish the tendency and desire to sin which we flawed humans find within our own souls.
Take a look at the site - there are a number of prayers to Saint Michael, as well as some really wonderful and interesting information about angels, and the spiritual warfare we are all engaged in.
