Intercession is a prayer of petition that participates in the intercession of Christ with the Father (CCC 2634). While Jesus is the one intercessor, Christians are also able to intercede on behalf of others, recognizing no boundaries or distinctions (CCC 2636). This form of prayer is rooted in the mercy of God, a reality evident from the time of Abraham to the present age (CCC 2635).

The practice of intercession is modeled after figures in salvation history who demonstrated bold confidence in God’s compassion. Abraham’s intercession serves as an early example of this confidence (Genesis 18:1-33, CCC 2571-2572). Similarly, Moses’ intercessory prayer, motivated by his intimacy with a God who is slow to anger and abounding in steadfast love, provides a model for future intercessors in both Judaism and Christianity (Ps 86:15, CCC 2574). King David further exemplified this by praying in the name of others, highlighting the importance of communal prayer (CCC 2565), while the fervent prayer of Elijah demonstrates the power of such intercession (James 5:17-18).

Intercession is deeply connected to the doctrine of the Communion of Saints, serving as a powerful tool of communion that unites believers and allows them to share in the hopes and sufferings of others (CCC 2683). As the Body of Christ, the Church is united with the intercession of her Head, Christ, for all humanity (CCC 1369). This communion allows for intercession through the lives and writings of recognized saints (CCC 2683), and the Church specifically encourages praying with Mary by entrusting prayers to her intercession.

In a liturgical context, the Apocalypse is a celebration that includes the intercession of martyrs and saints who have entered the Kingdom (CCC 2642). The Church on earth participates in this heavenly liturgy through faith, petition, and intercession (CCC 2642). For the individual Christian, the act of supplication reflects human vulnerability and the need for help, yet it encourages the believer to present requests to God with perseverance and confidence in His infinite love and mercy. Ultimately, this form of prayer cultivates an attitude of charity and gratefulness, serving as a witness to the love of God (CCC 2565).
