 the rosary, the number 150, corresponds to how many Hail Marys there were for each set. So we've got five sets of ten Hail Marys for the joyful, for the sorrowful, and for the glorious. So that's where that number 150 comes from. And Pope John Paul II goes on to say this. He says, I believe, however, that to fully the Christological depth of the rosary, it would be suitable to make an addition to the tradition.
