No one’s asking anyone to condone error.
But haughty self-righteous, critical-spirit judgmentalism; bad-faith sanctimonious hostility and abusiveness are not fruits of The Spirit.
And, timing and context are important as well as tone.
I think there IS a time for passers by to arrest the child-molester or murderer or wife beater etc.
But for a grubby homeless alcoholic to rise out of the gutter and self-rightously with great hostility, smugness, pique, sanctimony etc. insist on straightening the collar of the nun in the white habit . . . is . . . a bit much.
. . . more than a bit.
Great image. The problem is, it's never clear which one is the drunk, and which one is wearing the white collar. Each one thinks the other is the drunk.
One prophylactic I try to adopt is to avoid setting out to save people from their errors. I drop this scheme when their errors involve misstating and mocking what I believe.
For the rest, see my tag line. It ain't pretty, but it's accurate.
Agnus dei, miserere nobis.
I beg your pardon! I am NOT grubby.
