Whilst I have not looked at all of the coverage and so cannot vouch for its quality, I do recommend the following two:
BBC Radio 4 "You and Yours"
St Thérèse of Lisieux: Mgr Keith Barltrop 31 July 09
National Co-ordinator of the relics' visit, Mgr Keith Barltrop, on 'You and Yours'.
You can listen to the full "package", which is both very sympathetically presented and very informative. "You and Yours" is a daily consumer/general interest magazine programme on Radio 4; it is quite unusual for them to cover a religious topic.
'Through the visible to the invisible’ 27 Sept 08 by Mgr Keith Barltrop,
Chairman of the national organising group for the visit of the relics of St Thérèse to England and Wales, wrote an article in The Tablet on the visit.
"Pilgrimage is a big draw for people today, and this is a kind of pilgrimage in reverse, whereby a holy person comes to us rather than we to them. That is why the visit of the relics of St Thérèse of Lisieux to England and Wales next year has been conceived as an opportunity to reach out to spiritual seekers of all faiths or none, who may actually be far more open to such things than we realise."
