Possibly one of my readers can help me answer this liturgical question. There is a priest in my diocese that helps out at different churches and every time he says Mass on a day where the profession of faith is required he says the Apostles Creed and not the Nicene Creed. Now my understanding is that under the new missal that the Apostles’ Creed may be used during Lent, Easter and at Masses for Children.
Looking at a Zenit’s answer about this is the relevant section.
"19. Loco symboli nicaeno-constantinopolitani, praesertim tempore Quadragesimae et tempore paschali, adhiberi potest symbolum baptismale Ecclesiae Romanae sic dictum Apostolorum" (Missale Romanum, Page 513).
Knowing very little Latin this doesn’t help me much, but they say it could possible be interpreted
The Roman Church’s baptismal creed, the so-called Apostles’ Creed, may be used in place of the Nicene-Constantinopolitan Creed, especially in Lent and Eastertide."
Which widely interpreted could mean every Sunday, solemnity, etc.
My main question would be what would be a good reason for this substitution? Every time I have seen this done it greatly confuses those in the pews and people start mumbling their way through the creed since they expect one and try to recite the other and end up saying neither. Now I can see possibly doing this during Lent since this might be similar to suppressing the Gloria as something somewhat penitential. The first Mass I heard this done was on Trinity Sunday and I thought how totally inappropriate it was to not have the Nicene Creed with its great expression of the three persons of the trinity.
