The prescribed work

Historical reference: receive Communion and pray for the worldwide spread of the Gospel, under the usual conditions.
The Pope’s announcement invited the Rosary for that intention; the diocesan notice describes prayer more broadly.
This event-specific concession is not an annual permanent grant.
The Korean bishops’ notice explicitly limits the work to 18 October. Later completion of sacramental conditions does not extend the indulgenced occasion into November.

The work and its conditions

A plenary indulgence also requires complete detachment from every sin, sacramental confession, Holy Communion, and prayer for the Pope’s intentions, subject to the grant’s stated exceptions. The ordinary limit is one plenary indulgence per day.

Conditions common to every indulgence

The person gaining an indulgence must be baptized, not excommunicated, and in the state of grace at least when the prescribed works are completed. There must be at least a general intention to gain indulgences, and the prescribed work must be performed at the time and in the manner required by the grant.
