I was so happy to be able to receive Holy Communion on the tongue at the Oxford Oratory yesterday. Oxford is in the Birmingham archdiocese (or can the Oratorians make their own rules? I don't know), while I live in the Clifton diocese. Here it is forbidden to have any contact at the sign of peace, forbidden to receive Holy Communion from the Chalice, and forbidden to receive the Host on the tongue.
I can live very happily with the more peaceful sign of peace, in which, at most, people nod and smile to one another; and I don't receive from the Chalice anyway, because I want to give witness to the Church's teaching that Christ is received whole and entire, Body, Blood, Soul and Divinity, under either species alone. I fear that a good many people have been confused into thinking their Holy Communion is not complete without receiving from the Chalice.
A good many things changed for me when Summorum Pontificum was issued. Among the changes, I returned to the habit of receiving Holy Communion on the tongue. And now it has been forbidden, as a precaution against swine flu. I find it rather distressing, and one of the most troubling things is not knowing how long the ban is going to continue.
