Communion is when a person receives the body and blood of Christ (Holy Eucharist) into themselves via bread and wine.
“Those who have been raised to the dignity of the royal priesthood by Baptism, and configured more deeply to Christ by Confirmation, participate with the whole community in the Lord’s own sacrifice by means of the Eucharist.”
– The Catechism of the Catholic Church
Please note: “All celebrations of Baptism, First Eucharist, First Reconciliation and Confirmation are postponed until the Chief Medical Officer has advised that the Pandemic has ended, so Sacramental Preparation classes for both children and adults are cancelled”.
