   “Upon principle it is his aim to exhibit integrity of dealing, honest and godly sincerity to all men; if he fail, it must be in degree, it cannot be in kind; for a false and untruthful mind can never rightly know God; the more we know of him, the more upright and ingenuous, and liberal, and kind, and humane, and generous, must be our conduct to man.”

2. Pertaining to falsehood; corrupt; dishonest.

   “But what was our astonishment when the “Seven Letters by Anglicanus” made their appearance amongst us, accompanied by the report that you—one of our brethren—was the author of that untruthful, bitter, and malignant publication!”
