Father Mark Kirby's Chaplet for Priests is a beautiful, POWERFUL, easily memorized prayer. The POWER of the prayer comes from the Precious Blood of Jesus.
Each individual part of the prayer lends itself well to prayerful repetition. A very busy person, who has a desire to spiritually support priests, could make a habit of repeating these prayers (or a favorite one of them) throughout the day--even when it's not possible to pray the entire chaplet or to keep count on rosary beads. The prayer time possibilities are as numerous as an individual's ingenuity: while driving, while doing dishes, before meals, after meals, on awakening in the morning, before bedtime, before Mass, after Mass, after Rosary decades, etc., etc., etc.
Since we are supposed to "pray always", why not let it be for priests during this special Year of the Priest! What IS important is the lifting up of our minds and hearts to God in supplication for our priests. A time set aside for personal daily prayer is very important, but why waste the other numerous opportunities for turning to God as we go about our daily duties? If you have trouble remembering to pray in this way, ask the Holy Spirit and the Blessed Mother to remind you. You might be surprised at how often you are reminded-- an indication of God's will for you.
