The sign reminds us both of the death of Jesus and of what it means. When we receive the sign, then we are able, by faith, to receive the promise of redemption which the sign points to. However the Article also states the social aspect of the sacrament. It is a sign of the fellowship and love shared by those who gather around the same table as the Lord.

Anglicans believe that the bread and wine does not change during the Holy Communion service. The bread and wine are signs of the body and blood of Christ. They represent God’s forgiveness and the eternal life that results from his death.
The doctrine of transubstantiation contradicts the nature of a sacrament because it teaches that the sign is the same as the thing signified. According to the last rubric in the service of Holy Communion, the body and blood of Christ are not physically present because they are in heaven.

That is why, in the Holy Communion service, the body of Christ is received only in a spiritual manner, only by faith.
In the Service of Communion for the Sick, in the Book of Common Prayer, it is stated that if a sick person is unable to receive the sacrament by mouth, they are still able to eat and drink the body and blood of the Lord if they repent and believe and give thanks for Christ’s redemption, ie they eat and drink by faith.

The Article also says that the sacrament must not be kept after the service has finished. The reason is so that it will not be worshiped.
