**No one except the Holy Father has the authority to outright ban reception on the tongue. ** I would hope that those in any parish where the Bishop or Pastor has discouraged the practice would talk with their Pastor about H1N1 and reception on the tongue to ensure that they are able to continue to receive Holy Communion on the tongue as is their right.
If your Pastor has outright banned it, then those who wish to receive on the tongue need to talk to Father.
As far as banning the chalice, removing holy water, and so forth, I understand the need to protect the Faithful, but it also, IMHO, diminishes our faith. If Christ is TRULY present in the elements of the wine, and it truly has become his most Precious Blood, then it would be rendered incapable of spreading disease.
