*Should I bow during the Nicene Creed at the part where we say, “By the power of the Holy Spirit, He was born of the Virgin Mary and became man.”? *
A bow of the body, or profound bow, is made: toward the altar if there is no tabernacle with the Blessed Sacrament; during the prayers “Almighty God, cleanse” and “with humble and contrite hearts”; with the Profession of Faith at the words “was incarnate of the Holy Spirit … made man”…
Should I bow profoundly before reaching the altar to receive the Eucharist? Should I genuflect?
The posture for the reception of Holy Communion in the dioceses of the United States is standing. Each communicant bows his or her head before the sacrament as a gesture of reverence and receives Holy Communion from the minister. The consecrated Host may be received either on the tongue or in the hand at the discretion of each communicant. When Holy Communion is received under both kinds, the sign of reverence is made before receiving both the Body and the Blood of Christ.
*I choose not to drink from the cup of blood. Should I respectfully genuflect or bow profoundly before the cup or simply walk by? *
If you are not receiving from the cup, no sign of reverence is required.
