In Dublin, Roman Catholics when passing a Catholic church (or 'chapel') remove the hat or cap for a moment as a mark of respect, and usually utter a short aspiration or prayer under breath. This custom is I think spreading.
When one expresses his intention to do anything even moderately important, he always adds 'please God.' Even in our English speech this is of old standing. During the Irish wars of Elizabeth, it was told to an Irish chief that one of the English captains had stated he would take such and such a castle, when the chief retorted, 'Oh yes, but did he say please God': as much as to say, 'yes if God pleases, but not otherwise.'
'This sickness kept me from Mass for a long time; but with the help of God, I'll venture next Sunday.' 'Yes, poor Kitty is in great danger, but with the help of God she will pull through.'
'I am afraid that poor Nellie will die after that accident.' 'Oh, God forbid,' is the response.
People have a pleasing habit of applying the word blessèd [2-syll.] to many natural objects, to days, nights, &c. 'Well, you have teased me terribly the whole of this blessèd day—you young vagabone.'
'Were it not that full of sorrow from my people forth I go,
By the blessèd sun 'tis royally I'd sing thy praise Mayo.'
Translation of Irish Song on 'The County Mayo.'
A mother says to her mischievous child, 'Oh blessèd hour, what am I to do with you at all at all!'
'Oh we're in a precious plight
By your means this blessèd night.'
(Repeal Song of 1843.)
