As a Roman Catholic, I have known/prayed these songs for nearly all my life. They are the prayers that are repeated when praying the holy rosary, that prayer form which is so precious to Blessed Mother. In her apparitions, she instructs us to pray the rosary. It's very powerful. I have seen it work in my own life as well as for others. The power of prayer is not to be underestimated. Why am I singing the prayers? St. Augustine, a Doctor of the Church, said that when we sing, we pray twice.
When I recorded these today, I already had melodies to use for the first two prayers. However, for the "Glory Be" prayer I had no particular melody in mind. The Holy Spirit directed my singing for that one, right on the spot!
