A few years ago I was inspired by a little book by Fr. Anthony Gittins, The Presence that Disturbs. The title refers to the great 1798 Wordsworth  poem on Tintern Abbey:

…And I have felt
A presence that disturbs me with the joy
Of elevated thoughts; a sense sublime
Of something far more deeply interfused,
Whose dwelling is the light of setting suns,
And the round ocean, and the living air,
And the blue sky, and in the mind of man,
A motion and a spirit, that impels
All thinking things, all objects of all thought,
And rolls through all things…

I was delighted to find Anthony Gitten’s keynote address at the 2012 LA Religious Ed conference is available on youtube. Well worth 50 minutes.
