At a charismatic healing service by Fr Ralph Diorio, back in 1976, I saw a little five year old girl healed. It was awesome, but I also learned that many people did not see it. Why ? I have no idea, other than being grateful to God for allowing me to see it.
At Lourdes on the first night, there were 20,000 people with lighted candles, in procession from the Grotto around to the esplanade in front of the Basilica of the Immaculate Conception. The event brought tears to our eyes. We prayed a decade of the Holy Rosary alternating between Italian and English. It was Italian.English week at Lourdes. In between each decade, the Lourdes choir sang a hymn. When the sang Ave Maria, it was heaven touching earth. It was everything I saw in film and photos growing up in the 1950s. coming to life, only this was 1998.
God may not be calling you to either. Instead, He may be calling you to just attend a week-end retreat at a monastery.
God leads, we follow.
