Do you sprinkle?

That may sound like a rather personal question but I ask in all innocence.

                                            Is this "Sprinkle" or "Asperges"?

You see the Ordinariate have a pilgrimage at Walsingham underway and, it appears that "sprinkling" is part of it.

See the programme from Tenow8 blog below:-

Noon – Angelus and Solemn Mass at the National Shrine

2:30pm – Holy Mile and Rosary Procession to the Anglican Shrine.

3:15pm – Sprinkling at the Anglican Shrine

Pilgrims are invited to bring a picnic lunch.

This pilgrimage will be led by Monsignor Keith Newton.

I have two questions. One, what are they doing at the Anglican Shrine?

And two, what is sprinkling? Do they mean "Asperges"?

I trust that it does not have a sinister meaning (?) and, I do not wish to pour water (aherm) on this pilgrimage but it would be good to have a clarification of sorts.

The nub of what I am trying very clumsily to say is that, if the Ordinariate members have converted to the Catholic Faith shouldn't Anglican language and customs be ditched in favour of Catholic ones?
