And, after all, the _moral_ features of this interesting character constitute its principal charm. The integrity and manliness of Frederick Douglass, potent and acknowledged where he is at all known, have much to do with his influence as a popular orator. It has been customary, with a certain class of Shibboleth-pronouncers to class him with infidels, but this is only the appropriate and characteristic retort of a certain sort of “highly respectable” Christianity to his uncompromising denunciations of its hollow and selfish character. _I_ think Frederick Douglass is a Christian; he is a gentleman, I _know_. There are few white men of my acquaintance, who could have borne so much adulation, without losing the balance of their self-appreciation. Nobody ever knew Frederick Douglass to over-rate himself, or to thrust himself anywhere where he did not belong, or upon anybody who might by any possibility object to his companionship,--unless, in the latter case, when he deemed necessary the assertion of a simple right. Whence he got his retiring and graceful modesty, and his nice sense of the minute proprieties,--unless it be somehow in his _blood_,--is a mystery to me. Can it be possible that such refinements are _scourged_ into men “down South?” An illustration of this may be seen in his response to those gentlemen of Rochester, who, by way of gratifying a grudge against the Anti-slavery faction of their party, nominated Douglass for Congress in derision. “GENTLEMEN:--I have learned with some surprise, that in the Whig Convention held in this city on Saturday last, you signified, by your votes, a desire to make me your representative in the Legislature of this State. Never having, at any time that I recollect, thought, spoken, or acted, in any way, to commit myself to either the principles or the policy of the Whig party; but on the contrary, having always held, and publicly expressed opinions diametrically opposed to those held by that part of the Whig party which you are supposed to represent, your voting for me, I am bound in courtesy to suppose, is founded in a misapprehension of my political sentiments.
