We have the dismissal after the period of silence after the homily. And our priest has a long period of silence. And there are many things that might happen at mass between the homily and the creed. Just look in the Book of Blessings.
None of which apply to normal Sunday Mass. If we are doing the Dismissal in the middle of a wedding, funeral, or baptism, we’re good to go with that, but that’s not the normal scenario.
And what about the fiasco of the Scrutinies? The Scrutinies have to use the readings of Year A, even if it is
not Year A. So what is the priest supposed to do? He can do the Year A readings, except that throws the regular parishioners off of their track, and none of what they are doing in their home devotions (Liturgy of the Hours, Lenten prayer booklets, etc.) makes any sense. Or, he can do the proper readings of the year, and then none of the prayers for the Scrutinies make any sense, because they are based off the idea that the readings of Year A have just been read out.
PS: Don’t get me wrong - I toe the party line when I’m working in the RCIA, and I make everyone do it according to the book - I stand on the priest’s foot, get right in his face, and force him to do the Year A readings throughout Lent, because that’s what it says to do in the book. But I have to say, I don’t like it any more than he does, and the reasoning behind it escapes
both of us.
Why set up so much confusion? The RCIA participants hate the whole thing, anyway. They’d much rather hide in their classroom downstairs than be paraded around the Church for the Scrutinies - most of them don’t even show up on those days, just to get out of it. (And yes, I call them on it and I give them heck for being absent. I know my place, and I don’t buck the system.)
