Catholic Devotional Piety
Catholic piety is based on the life and teaching of Jesus Christ. Although Jesus along with the Father, and the Holy Spirit is the focus of Catholic faith, Jesus was also the founder.
The fundamental relationship of Jesus Christ, Son of God is with his Father. As Son, Jesus is always in communion with God the Father. All throughout his life, his prayer starts with "Father', and the prayer he taught his disciples starts with "Our Father".
From this the Catholic Church has developed a piety that mirrors Jesus's attitude. The Mass, the central prayer of the Church, also refers to the Father.
