I always thought you needed these things to gain a plenary indulgence.
- Prayers for the Pope.
- Detached from sin.
- Pray the Rosary.
However it seems that many Catholic sites state that only the first four are needed to gain the plenary indulgence so why do we (or is it just me) pray the Rosary for the indulgence?
I know that praying the Rosary is great but wonder whether it is needed for the indulgence.
