There is no greater guarantee of a racist sentiment than the opening "I'm not being racist..." And the louder the protest, the more we worry about the diatribe to follow.
But there's a preaching equivalent. Last week I listened to many online sermons by the great and good and I repeatedly heard this phrase:
"Now, I don't mean this legalistically, but..."
I must have heard the saying about a dozen times in 5 sermons. In one instance it was prefaced by this nugget of reformation gold: "Obedience opens up the channels by which God's grace may flow."
...But not in a legalistic way you understand.
Protests that "I'm not being a legalist" do not exempt you from the charge. To my mind they only raise greater suspicion.
