The 1979 Prayer Book gives the option of standing or kneeling. Standing symbolizes standing with the risen Lord and kneeling symbolizes reverence to the present Lord. Do this for the remembrance of me. Whenever you drink it, do this for the remembrance of me. The Holy Eucharist meal consists of bread and wine.
Bread is basic to life and symbolizes the fruit of the earth.
It also symbolizes our labor in the effort it takes to grow and harvest the grain, to make flour, and to bake bread. Bread is essential to human life and in Hebrew, the words for 'bread' and 'life' sound almost identical. Wine also symbolizes the fruit of the earth and it symbolizes our labor in growing grapes and making wine. Whereas bread symbolizes survival, a food necessary to stay alive, wine is associated with joy, fellowship, laughter, refreshment, and relaxation. This added a new dimension to the ancient Hebrew rite of table blessing.
