When are we supposed to bow during Mass? Are we to bow at the name of Jesus, Jesus Christ, and Christ?
According to the General Instruction, n. 234:
a)A bow of the head is made when the three Divine Persons are named to gether and at the name of Jesus, Mary, and the saint in whose honor Mass is celebrated.
b)A bow of the body is made before the altar, if the blessed sacrament is not present; at the prayers, Almighty God, cleanse, and Lord God, we ask you to receive; in the profession of faith at the words, by the power of the Holy Spirit, in the Roman canon at the words, Almighty God, we pray. The same kind of bow is made by the deacon when he asks the blessing before the gospel. The priest, moreover, bows slightly when he says the words of the Lord at the consecration.
The GIRM says to bow at the name of Jesus. We have not seen documentation that distinguishes between Jesus and Jesus Christ. Traditionally, bows were made at both and we believe that the rubric covers both phrases. Christ is not Jesus' name, but rather a title meaning annointed, so one would not bow at this time.
