From the Anglican Catechism
108. Why did Christ institute the sacrament of Holy Communion?
He instituted it for the continued remembrance of the sacrifice of his atoning death, and to convey the benefits the faithful receive through that sacrifice. (Luke 22:17-20; 1 Corinthians 10:16-17)
109 What is the outward and visible sign in Holy Communion?
The visible sign is bread and wine, which Christ commands us to receive. (1 Corinthians 11:23)
110 What is the inward and spiritual thing signified?
The spiritual thing signified is the body and blood of Christ, which are truly taken and received in the Lord’s Supper by faith. (1 Corinthians 10:16-18; 11:27; John 6:52-56)
111 What benefits do you receive through partaking of this sacrament?
As my body is nourished by the bread and wine, I receive the strengthening and refreshing of my soul by the body and blood of Christ; and I receive the strengthening and refreshing of the love and unity I share with fellow Christians, with whom I am united in the one Body of Christ. (1662 Catechism)
112 What is required of you when you come to receive Holy Communion?
I am to examine myself as to whether I truly repent of my sins and intend to lead the new life in Christ; whether I have a living faith in God’s mercy through Christ and remember his atoning death with a thankful heart; and whether I have shown love and forgiveness to all people. (1 Corinthians 11:27-32)
263 How does the Lord’s Supper enable you to continue learning and living God’s Law?
In the Lord’s Supper or Holy Eucharist, I hear the Law read, hear God’s good news of forgiveness, recall my baptismal promises, have my faith renewed, and receive grace to follow Jesus in the ways of God’s Laws and in the works of his Commandments.
