The Seven Sisters Apostolate is a call to women to strengthen the Church by ensuring that a Holy Hour is prayed each day of the week for the sole intention of a specific priest or bishop—a “holy wasting” (cf. Mt. 26:10) or lavishing of prayer for his ever deeper conformity to Christ. Each member commits to a Holy Hour on a distinct day of the week, thus covering a complete week.
The Holy Hour is ideally prayed in the presence of the Blessed Sacrament – either in an Adoration Chapel or in front of a Tabernacle – but not restricted to the parish of which the Seven Sister is a member. This generous commitment of one hour per week of prayer is asked for a period of one year but can remain open-ended in time as each individual discerns her call to continue. The normal commitment extends from June to June, the month of the Sacred Heart.
You can serve as a primary member or as a substitute. As the name implies, primary membership of this Apostolate is open only to women. However, men can serve as substitutes.
