16. Your guardian angel
Forgotten about this one since you were a kid? From St. Frances of Rome to Padre Pio, many adult Saints had extraordinary relationships with their guardian angels. Our dealings with our guardian angels may be ordinary, but we should never ignore the great guide entrusted to us whom Jesus says “always look[s] upon the face of my heavenly Father” (Mt 18:10).
17. The angel of your town or city
Tradition teaches that the great angels called Principalities watch over individual towns and cities. Both Peter Kreeft and Cardinal Jean Danielou have reliable books on the matter. Invoking the Principality of the place in which you’re praying is not only spiritually honorable but an easy way to remind yourself of the vast love of God’s spiritual world.
18. The Saint of the church you attend
Whether it’s St. Cyril’s of Alexandria or St. Patrick’s, your home church is likely named after a Saint. Praying with that Saint before Mass or activities there invokes a powerful patron.
