Okay, let's take a look at a few specific prayers prayed to Saint Ann (the mother of Mary):
DAILY PRAYER TO SAINT ANN
O glorious St. Ann, you are filled with compassion for those who invoke you and with love for those who suffer! Heavily burdened with the weight of my troubles, I cast myself at your feet and humbly beg of you to take the present intention which I recommend to you in your special care.
Please recommend it to your daughter, the Blessed Virgin Mary, and place it before the throne of Jesus, so that He may bring it to a happy issue. Continue to intercede for me until my request is granted. But, above all, obtain for me the grace one day to see my God face to face, and with you and Mary and all the saints to praise and bless Him for all eternity. Amen.
Our Father, . . . Hail Mary . . .
O Jesus, Holy Mary, St. Ann, help me now and at the hour of my death.
Good St. Ann, intercede for me.
Would anyone pray such things to a family member or friend here on earth?
Or how about this example, to Saint Ann as well:
Dear St. Ann, though I am but a prodigal child, I appeal to you and place myself under your great motherly care. Please listen to my prayers and grant my requests. See my contrite heart, and show me your unfailing goodness.
Deign to be my advocate and recommend me to God’s infinite mercy. Obtain for me forgiveness of my sins and the strength to begin a new life that will last forever.
Blessed St. Ann, I also beg of you the grace to love, to serve, and to honor your daughter, the most holy Virgin Mary. Please recommend me to her and pray to her for me. She refuses none your requests but welcomes with loving kindness all those for whom you intercede.
Good Jesus, be merciful to the faithful servants of Your grandmother St. Ann.
One more example:
Hail, all-powerful Lady. By God’s special favor, grant consolation to those who invoke you. Procure for them the eternal riches of heaven, and like a good mother, success in their temporal affairs as well.
Good St. Ann, obtain my deliverance from the punishment which my sins deserve. Obtain for me success in my temporal affairs; especially see to the salvation of my soul.
St. Ann, by your influence with Mary’s son Jesus, you have won the gift of conversion for many sinners. Will you then abandon me, who have chosen you as my mother? No, St. Ann. Your name alone, which signifies grace, assures me of the help of your prayers, and these prayers will surely procure pardon and mercy from Jesus. You will pray for me now and at the hour of my death.
Again, would anyone be comfortable saying such things to a family member or friend? How is this not giving praise to a fellow (departed) human being, that God alone deserves?
