St. Patrick, pray for us.

I arise today 
Through a mighty strength, the invocation of the Trinity,
Through belief in the Threeness,
Through confession of the Oneness of the Creator of creation . . .

Read the rest of the prayer attributed to St. Patrick [and called "St. Patrick's Breastplate"] here.

With no time to write a longer post, I outsource the hymn, "Hail, Glorious St. Patrick," to the late Irish tenor, Frank Patterson.

And, yes, I am wearing green today. And I've advised my Protestant friends, as they value my friendship, not to wear orange. Being relatively peaceable and having read some history with me over the years, they kindly complied. No injuries.
From Ireland's troubled history comes this (and many another) reflection on religious and political freedom:

You may take a shamrock from your hat and cast it on the sod,

It will take root and flourish there though underfoot it's trod.

When law can stop the blades of grass from growin' as they grow,

And when the leaves in summer-time their verdure dare not show,

Then will I change the colour, too, I wear in my caubeen

But 'till that day, please God, I'll stick to wearin' o' the Green.

Happy St. Patrick's Day.
