Christian Perfection [EPUB ebook] 

There is scarce any expression in Holy Writ which has given more offence than this. The word perfect is what many cannot bear. The very sound of it is an abomination to them. And whosoever preaches perfection (as the phrase is, ) that is, asserts that it is attainable in this life, runs great hazard of being accounted by them worse than a heathen man or a publican.

And hence some have advised, wholly to lay aside the use of those expressions, “because they have given so great offence.” But are they not found in the oracles of God? If so, by what authority can any Messenger of God lay them aside, even though all men should be offended? We have not so learned Christ; neither may we thus give place to the devil. Whatsoever God hath Spoken that will we speak, whether men will hear or whether they will forbear; knowing that then alone can any Minister of Christ be “pure from the blood of all men, ” when he hath “not shunned to declare unto them all the counsel of God.” [Acts 20:26, 27]
