How many have prayed the prayer of Tobias? Tobias 8 = Douay-Rheims Bible
Tobias burneth part of the fish’s liver, and Raphael bindeth the devil. Tobias and Sara pray.
 And after they had supped, they brought in the young man to her.  And Tobias remembering the angel’s word, took out of his bag part of the liver, and laid it upon burning coals.  Then the angel Raphael took the devil, and bound him in the desert of upper Egypt.  Then Tobias exhorted the virgin, and said to her: Sara, arise, and let us pray to God today, and tomorrow, and the next day: because for these three nights we are joined to God: and when the third night is over, we will be in our own wedlock.  For we are the children of saints, and we must not be joined together like heathens that know not God.
 So they both arose, and prayed earnestly both together that health might be given them,  And Tobias said: Lord God of our father, may the heavens and the earth, and the sea, and the fountains, and the rivers, and all thy creatures that are in them, bless thee.  Thou madest Adam of the slime of the earth, and gavest him Eve for a helper.  And now, Lord, thou knowest, that not for fleshly lust do I take my sister to wife, but only for the love of posterity, in which thy name may be blessed for ever and ever.  Sara also said: Have mercy on us, O Lord, have mercy on us, and let us grow old both together in health.
 And it came to pass about the cockcrowing, Raguel ordered his servants to be called for, and they went with him together to dig a grave.  For he said: Lest perhaps it may have happened to him, in like manner as it did to the other seven husbands, that went in unto her.  And when they had prepared the pit, Raguel went back to his wife, and said to her:  Send one of thy maids, and let her see if he be dead, that I may bury him before it be day.  So she sent one of her maidservants, who went into the chamber, and found them safe and sound, sleeping both together.
 And returning she brought the good news: and Raguel and Anna his wife blessed the Lord,  And said: We bless thee, O Lord God of Israel, because it hath not happened as we suspected.  For thou hast shewn thy mercy to us, and hast shut out from us the enemy that persecuted us.  And thou hast taken pity upon two only children. Make them, O Lord, bless thee more fully: and to offer up to thee a sacrifice of thy praise, and of their health, that all nations may know, that thou alone art God in all the earth.  And immediately Raguel commanded his servants, to fill up the pit they had made, before it was day.
I haven’t. As a Presbyterian, I have never studied the Catholic Bible nor seen nor even heard this prayer.
Before answering I Googled it and found this: http://lectorprep.org/occasional/tobiah_and_sarah_prayer.html
I am not in the RCC, but I read this book some time back and noticed the part about using fish to excorcise demons. I wonder if that sort of thinking is where the idea that garlic is supposed to repel vampires comes from.
If I find myself having to cast out a demon, I’ll command it to go in the name of Jesus rather than use fish.
