Catholic Truth Online

Prayers of intercession are another form of prayers of petition, but they are important enough to be considered their own type of prayer. As the Catechism of the Catholic Church notes (Para. 2634), "Intercession is a prayer of petition which leads us to pray as Jesus did." In a prayer of intercession, we're not concerned with our needs but with the needs of others. Just as we ask the saints to intercede for us, we, in turn, intercede through our prayers for our fellow Christians, asking God to shower His mercy on them by answering their requests. A Prayer of Parents for Their Children and these Weekly Prayers for the Faithful Departed are good examples of prayers of intercession for the needs of others
