*"The Profession of Faith
** 67**. The purpose of the Symbolum or Profession of Faith, or Creed, is that the whole gathered people may respond to the word of God proclaimed in the readings taken from Sacred Scripture and explained in the homily and that they may also call to mind and confess the great mysteries of the faith by reciting the rule of faith in a formula approved for liturgical use, before these mysteries are celebrated in the Eucharist.
** 68**. The Creed is to be sung or said by the priest together with the people on Sundays and Solemnities. It may be said also at particular celebrations of a more solemn character.
If it is sung, it is begun by the priest or, if this is appropriate, by a cantor or by the choir. It is sung, however, either by all together or by the people alternating with the choir.
If not sung, it is to be recited by all together or by two parts of the assembly responding one to the other.* "

“
69. In Holy Mass as well as in other celebrations of the Sacred Liturgy, no Creed or Profession of Faith is to be introduced which is not found in the duly approved liturgical books.”
My only question is that in *
Redemptionis Sacramentum, ***it is not completely clear what "
duly approved liturgical books" are?
Anyone out there able to clarify this? Sometimes I think church documents purpusfully allow “wiggle room” by not being too specific.
