In the Binnacle

The Church's compass, if you please,
Has two or three (or more) degrees
Of variation;
And many a soul has gone to grief
On this or that or t'other reef
Through faith unreckoning or brief
Miscalculation.
Misguidance is of perils chief
To navigation.

The obsequious thing makes, too, you'll mark,
Obeisance through a little arc
Of declination;
For Satan, fearing witches, drew
From Death's pale horse, one day, a shoe,
And nailed it to his door to undo
Their machination.
Since then the needle dips to woo
His habitation.
