Attending the in-person celebration of Sunday Mass and receiving Jesus in the Eucharist are vital to our lives as Catholic Christians. We were created for Communion. Whether you are returning to your home parish, or seeking a local parish on vacation, your participation in the Mass unites you with the Church — the Body of Christ. This communion transforms us as persons and enables us to make manifest the Kingdom of God in our world. The celebration of the Eucharist truly is the source and summit of our faith.
