The solemn entrance to the church on Palm Sunday...

I wanted to clarify what is done at Saint-Eugène when the procession prepares to re-enter the church. 

The Missale Romanum (the pdf I have is of one from 1920) specifies that, after the Gloria, laus et honor is sung (by the chanters inside the church and the celebrant's party outside) when the procession has arrived back at the church, the subdeacon of the Mass then proceeds to strike the closed church doors with the processional Cross, upon which the doors are opened and the Ingrediente Domino is sung.

Postea Subdiaconus hastili Crucis percutit portam: qua statim aperta, Processio intrat ecclesiam, cantando:

℞. Ingrediénte Dómino in sanctam civitátem etc.

 

But at Saint-Eugène (the libellum, livret is here; this part of the day's Liturgy is on page 15 of the pdf), a 'rite proper to the Church of Paris, symbolising the opening of Heaven to mankind by the Sacrifice of Christ on the Cross' is used.

 

The celebrant strikes the door of the church three times with the Cross, singing:

Attóllite portas príncipes vestras, et elevámini, portæ æternáles ; et introíbit Rex glóriæ.

The chanters, from within the church, respond:

R/. Quis est iste Rex glóriæ ? 

The celebrant:

Dóminus fortis et potens, Dóminus potens in prælio : Attóllite portas príncipes vestras, et elevámini, portæ æternáles ; et introíbit Rex glóriæ.

The chanters:

R/. Quis est iste Rex glóriæ ? 

The celebrant:

Dóminus fortis et potens, Dóminus potens in prælio : Attóllite portas príncipes vestras, et elevámini, portæ æternáles ; et introíbit Rex glóriæ.

The chanters:

R/. Quis est iste Rex glóriæ ? 

The celebrant:

Dóminus virtútum, ipse est Rex glóriæ.

At this point, the doors of the church are opened, and all enter.

I must admit that I'm not quite sure who did what outside. I do recall that the veiled processional Cross, after the door-striking had happened and the doors were opened, was handed from one cleric to another: so don't know (without watching again) whether it was Fr Durodié or Fr Grodziski performing the celebrant's part for this particular solemn entry rite.
