Hello,
Today’s post is going to be a brief collection of links interspersed with my commentary because I think they contain material which is important for everyone to read! Also, the history behind the St. Michael the Archangel Prayer is fascinating and pertinent to the times in which we live. 
Here is an excellent piece written by Fr. William Saunders about St. Michael, and which mentions the St. Michael Prayer. Here is the text of the St. Michael Prayer from EWTN. Here is the link for a post, which speaks more about the St. Michael Prayer in particular from Church Militant. They give a lot of fascinating history.
I hope that you all enjoy reading these. The St. Michael Prayer is one of my favorite, and I am attempting to learn it in Latin at the moment. Catholic Answers has a fascinating article on their site which dissects some of the original Latin of the prayer and provides some more insight into the meaning of the Latin. I highly encourage reading this! It is available here.
God bless you all! And please – begin to pray the St. Michael prayer for the Church in our days.
