Which parish are you going to? All the Anglican Use parishes use Rite I of the BDW, except for St. Mary the Virgin in Arlington, TX. It uses Rite II which is really an adaptation of the NO.
I believe the Pastor uses this Rite because he is from England and in England Anglo Catholics use the NO. The early Mass in the AU Mass.
Once the Ordinariates are established and the new liturgy is completed I hope they will remove Rite II and also change the existing Rite I to be closer to the Anglican Missal. Rome added parts of the NO or if you like 1979 BCP, they are just some of the short responses, but in some ways harm the flow of the Anglican Use liturgy.
Hopefully you will be attending Our Lady of the Atonement in San Antonio. They will either have prayer books or some type of written form to follow.
Since I haven’t really attended one I can’t say if each one follows all the same traditions.
At. OLA when the crucifix goes by all kneel, maybe at others people just bow their heads. In Rite I you will be kneeling most of the time, except for the Gloria and Creed.
From the video it appears they bow their heads at the name of Jesus and I think of Mary. They also genuflect at the Incarnation in the Creed.
Please let us know how it went.
Yours in the Hearts of Jesus and Mary
